Why do we call it [A4 PLUS]?

The extended size of our 10 Pocket Binder Pages (234mm x324mm) necessitated the design of a larger binder (traditional 9 pocket binder with pocket size 67*92 has a page size of 225mmx290mm), leading to the creation of our A4 PLUS binder. We also plan to make it clear that our A4 PLUS pages may not fit in all A4 binders.

You will need to consider the larger size of the pages if you prefer to use your own binders.

Specifically, our K-KEEP A4 PLUS 10 Pocket Binder Pages are designed to support double sleeving with pockets measuring 62x93mm, purposefully engineered to perfectly accommodate double-sleeved cards of 61x91mm.

This Kpop double-sleeving system is like below:

The A4 PLUS 10 Pocket binder page is expected to be popular among both OT5 and OT10 collectors. Collectors can now display all members of these groups on a single page instead of facing the dilemma of choosing the least favorite member. 

Binder Math: The A4 PLUS binder comes with a 2-inch binder mechanism. We have found that it can hold more than double the cards a 1-inch A4 binder would hold.

When the K-KEEP A4 2-inch binder is with our 10 pocket pages, there is another capacity increase of 11% more storage (one more card for each page).

Between doubling the page capacity and adding an extra card per page, ours has 2.2 times the card storage capacity of a 1 inch A4 binder.

Our K-KEEP A4 PLUS Pro Binder is designed as a "Comprehensive Collector's Binder," meticulously tailored to cater to the wide-ranging needs of Kpop collectors. It incorporates 11 unique styles of A4 PLUS Premium Binder pages, adept at housing an array of collector items. These include standard photocards (55x85mm), tour postcards (70x100), standard postcards (100x150mm), mini posters (150x210mm), horizontal bookmarks, concert tickets, and much more.
