High quality
High quality, would’ve preferred less empty space.
High Quality but too big for what I was looking for, prefer a tighter fit for lezhin cards.
Very premium and beautiful. Should’ve read closer that it doesn’t come with any inserts. Assumed the ones I purchased would be on top of sheets that came with the binder at that price 😅 Will have to order more!
Very nice and sturdy. I like them a lot
Favorite standard size binder! Looks even more beautiful in real life the color is very light blush pastel blue color, all pcs pop and fit! Enhypen Enchin pcs will look great with blue! I hope they make more Standard size binders its great to separate eras and they look prettiest on the shelf and when opened compared to wide binders. Also perfect for smaller collections or to separate eras and collection, a big fan of ultbias! Quality irl is unreal!
Most beautiful Standard size binder! Excellent quality! Love standard binders, the pages look like a book! I hope they make more colors! I put Sunghoon early eras into this binder! They look soo much better than in any other binder! Thank you Ultbias, the collection looks so beautiful!
Favorite size pages! The cards look the best in this sizing, i tried all from ultbias and these are the best for me, the space between cards looks just right irl with these ones! Clear and thick, great quality too!
Very beautiful! Love standard size waiting forore standard size binders! More compact and look prettier! Perfect to separate different eras into binders/collections! Light blue pastel color accentuates pcs and inclusions without overpowering like some stronger colors!
good as always!
(World) [PRE-ORDER] Custom A4 9-Pocket Pages – V3 – Outer Size
Items arrived quickly - as described.
Beautiful design and amazing quality as always, it's perfect for my &team Nico collection, but the thickness of the binder rings makes it kinda hard to flip the pages, I've never had that issue with my astro and wanderlust duos which had the 4 instead of 3 rings

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.
