I have full set of BT21 binders and although they are branded "for BTS", we can easily use them for any collection.

Its such a cute binder, I cannot wait to fill it with photocards!
BT21 with ULTBIAS - CHIMMY - A5 myCOLLECTION - Complete Set (World)
The pocket pages are a perfect fit for standard photocards. They’re thick enough to make you feel like your PCs are well protected, yet crystal clear so every detail still shines through. They have a very premium feel and flipping through my collection is such a satisfying experience because nothing takes away from the clarity of the cards.
Before discovering UltBias, I used to protect my PCs with slim toploaders. However, the only pocket pages I could find locally that fit slim toploaders were so thick that they reduced the clarity of the photocards. I eventually switched my entire collection to these PC sleeves with the A4 9-Pocket V3 pages, and the photocards feel so secure that I no longer see the need to double-sleeve or use slim toploaders. I also enjoy flipping through my binders much more now because the photocards look so much clearer.
Its cute but its too complicated and the binder had some damage
It's a beautiful and well built binder. I love it! It's really sturdy and protects your precious collection very well. I only find that the amount of binder pages that fit in the binder when your collection is sleeved is less than is described, so if you count it out, you might need an extra binder. But other than that well worth the purchase
The pages are made of quality material (very durable) and secure my photo cards perfectly, with no sliding!
