A K-pop release almost always exists in several versions, published on the same day and sold at the same time. Knowing what a version is does not settle anything: you still have to pick one, often within days, during the preorder window. This guide is about method. It starts from the criterion to set before opening any page, reviews the five fields worth comparing, explains what a random draw changes, and ends with four steps to follow. pocabase describes 1.966 versions across 765 albums with those same fields, which is what makes them comparable.

Set your criterion before opening any page

The most common mistake is comparing before knowing what you are after. Version visuals look alike, inclusion lists run long, and the decision ends up being made on an impression. Set your criterion first, in one sentence. The common ones are few: getting the photocards of one specific member, owning the most complete object, spending as little as possible, or building a full collection for a group. Each leads to a different version of the same release.

That criterion has to be single, or at least ranked. Wanting both the most complete object and the lightest parcel means deciding nothing, because those two goals almost always pull against each other. Writing the criterion down before opening the pages changes the outcome: the comparison becomes a check, with a clear answer at the end, instead of hesitation that lasts right up until the preorder window closes on you.

A well-set criterion then translates into fields to read. A target member points to the inclusions and the photocard count. The most complete object points to the inclusions and the dimensions. The lightest parcel points to the weight and the format. A full collection points to the EAN, which let you confirm no version is missing. That translation is what makes a comparison quick, and its absence is what makes people hesitate for days.

The five fields to compare, version by version

A version page always carries the same information, which lets you compare without reading marketing copy. The format first, among the eight values recorded in the database: cd, poca, platform, vinyl, kit, cassette, digital, other. It tells you which family of object you are dealing with. Then the inclusion list, item by item, with quantities, the x out of y note when you only receive part of a set, and a flag on the items drawn at random.

Then come the photocard count announced for that version, and the weight in grams, which gives the real footprint and the difference between a case with a photobook and a card. Finally the thirteen-digit EAN, which identifies the version with no possible ambiguity. Two versions of one release always carry two different EAN, even when their names are close enough to be mixed up in a reseller listing or in a resale post.

Format: the object family, among the eight recorded values.
Inclusions: the detailed contents, with quantities and random draws.
Photocard count: announced for that one specific version.
Weight in grams: the real footprint and the shipping cost.
EAN: the identifier that never misleads, at a reseller included.

Random draws and the x out of y note

An inclusion can be fixed or random, and the gap between the two is large for anyone targeting one member. A fixed inclusion is the same in every copy of the version: you know exactly what you receive. A random inclusion is drawn at packing time: you get one card out of a set, with no way to choose. On pocabase, 62% of versions hold at least one item drawn at random.

The x out of y note says how wide the draw is: two photocards out of twelve does not mean the same thing as four out of five. The bigger the set and the smaller the number received, the lower the chance of getting one given member. An x out of y version therefore does not have the same practical value as a fixed-content version, even when both show the same total card count on the page.

The practical consequence is simple. If your criterion is one specific member, a fixed-content version holding that card beats two random ones. If no fixed version fits, you either accept the draw or go through fan-to-fan resale after the release, which sits outside the preorder frame entirely. Either way, the decision has to be made knowing the draw type, not discovered when the parcel arrives and the cards come out wrong.

The POB does not depend on the version

This point is widely misunderstood, and it skews many comparisons. A POB is attached to a reseller, not to a version: the database records it with its reseller, the item offered, a deadline and a region. One reseller often offers the same POB across every version of a release, and two resellers offer two different POB on the same version. The POB is therefore a separate criterion, handled after the version is chosen.

Order matters. Choose the version that answers your criterion first, then look at which resellers carry it and what POB comes with it. Doing the reverse leads to buying a version that does not suit you for a free item rarely worth that gap. Check the region of the POB and its deadline as well, which comes before the release: an offer announced elsewhere does not necessarily apply where you are delivered.

Five, six or seven versions: one, or the full set

Many recent releases exist in five, six or seven versions, sometimes more. In the pocabase database the most split release is THIS IS FOR by TWICE, with 14 versions listed. Faced with that number, two strategies exist and only one suits you. The first is choosing a single version against the criterion you set. The second is taking the full set, accepting the cost, the weight and the shelf space that go with it.

The single-version strategy nearly always wins when the budget is monthly and shared between several releases. It asks for one decision, it keeps the parcel light, and it leaves room for the next release. The full-set strategy is only justified by a collection goal you own up to, on one specific group, and on chosen releases: applied to everything, it drains a budget in two comebacks and fills a shelf in one year.

In between there is a middle option: taking two versions chosen for different reasons, one for its photobook and one for its photocards, for instance. That is fine when both reasons are written down in advance. What is not fine is adding a third version at checkout because the window is closing: that decision is not made on a criterion at all, it is made by the deadline instead of by you.

Single version: one decision, a light parcel, budget kept back.
Full set: only for a collection goal you have decided on.
Two versions: fine when each answers a written reason.
Last-minute addition: a decision made by the deadline, not by you.

The traps, and a four-step method

Three traps come up constantly. The first is buying two versions that hold the same photocard: series sometimes overlap from one version to the next, and only reading the inclusions shows it. The second is believing a more expensive version holds more cards: the price depends on the format, the photobook and the packaging, not only on the photocard count shown on the page. Two versions at the same price can list very different card counts.

The third trap is forgetting weight on an international parcel. A version with a disc and a photobook weighs several hundred grams, a card without a disc a few dozen. On pocabase, shipping is included in the displayed price, but the weight is still a reliable indicator of what you will receive and have to store. Across three or four versions ordered together, that gap shows on the parcel and on the shelf.

The method takes four steps, in this order, and a few minutes. It avoids the three traps above because it forces you to read the fields before looking at prices, and because it puts the POB in its real place: after the version is chosen, never before. Applied to every release, it makes the decision short and repeatable, even when the preorder window closes in two days and several versions look alike.

One: write your criterion in one sentence, before opening any page.
Two: compare format, inclusions, photocard count, weight and EAN.
Three: check the draw type, fixed or random, and the x out of y note.
Four: pick the reseller for its POB, its region and its deadline.

Häufige Fragen

How do I know how many photocards a version holds?

The count is recorded version by version and shown on the page, next to the format and the weight. The inclusion list then says whether those cards are fixed or drawn at random, and the x out of y note says how many you receive out of the whole series. Read both together, never one alone.

Can two versions hold the same photocard?

Yes, it happens: series sometimes overlap from one version to another, fully or in part. It is a classic trap when buying two versions to double your chances on one member. The only way to check before ordering is to compare the inclusion lists of both versions, line by line, on their pages.

Does a more expensive version hold more photocards?

Not necessarily. The price depends on the format, the thickness of the photobook, the packaging and sometimes on items unrelated to cards. The photocard count is a separate field, shown on the page of every version: compare that field directly rather than inferring anything at all from the price you are shown.

Does the POB change with the version I choose?

The POB depends on the reseller, not on the version. One reseller often offers the same item across every version of a release, and two resellers can offer two different POB on the same version. So choose the version first, then the reseller, checking the region of the POB and its deadline before ordering.

Should I buy every version of a release?

Only if your criterion is explicitly a full collection, on one specific group. Otherwise a single version chosen against a written criterion is enough, costs less, weighs less and leaves budget for the next release. Releases with five, six or seven versions make the full-set strategy hard to sustain over a year.
