About Duo Edition - A4 myCOLLECTION Binders
The Duo Edition is a 2-in-1 binder system for collectors who want maximum storage space without compromising on utility, protection or design. An ULTBIAS original solution, it comes with two individual custom A4 ring binders stored togeter in one shared outer case. In development for almost two years, the innovative design improves the overall management of larger collections by making it easier to access, organize and browse.
The Duo Edition is one of three sizes available in our Custom A4 myCOLLECTION Binder range. It offers the most photocard storage and can fit a total of x90 single-sided sheets of our Custom A4 9-Pocket Photocard Pages, which holds up to 810 photocards across both binders.
Each custom A4 4-D ring binder included is constructed with tough premium board core and equipped with a dual magnet clasp. This enclosure keeps the contents safe and gives the binder its signature box-like structure to ensure it can be stored standing without collapsing. The protective Binder Shield™ prevents pages from sagging when stored upright, supported by custom-engineered reinforced rings that can withstand up to 2kg of weight. Designed for everyday handling, the spine eyelet together with the ventilated holes on the outer case makes it effortless to quickly access and shelf your binder in one quick wobble-free motion.
With no fixed pages, tailor your binder to fit the exact needs of your collection with the flexibility to adapt and change your set up at any time. For the best fit and alignment, choose our archival-safe Custom A4 Pocket Pages.

An absolute highlight of my BTS collection! 💜
I preordered this ARMY binder and was so excited for it to arrive, but unboxing it exceeded my expectations! Everything was packed so carefully and protected so well for shipping. And the gorgeous special packaging… I was honestly speechless with happiness! 🥹💜 The unboxing itself felt like a little event.
I can’t wait to start organizing my photocards in it—or at least part of my collection! 😂 Thank you so much for this beautiful product and all the care put into the packaging. Absolutely worth the wait! 💜
These binders are just the best quality. I love knowing that all of my pcs are safe and displayed in a cute way. The sets of binders look amazing together. Highly recommended 🫶
The perfect binder for my Golden and I Am Still collection. Initially, I had them in a My Universe Deluxe A5, but when My Universe Part II came out, I knew this would be the perfect binder. I had so much fun arranging my PCs and Postcards here. Thank you so much!! 🥳🎉💜✨️
Right next to its lighter version, these were my first binders that made me decide to move over to A4s for my BTS inclusions. These are amazing quality, Ultbias! Thanks! 🎉🥳🎉🥳🎉🥳🎉
I love this binder! The purple color is so nice and vibrant and the designs on both the binder itself as well as the dust cover are super pretty, definitely the perfect binder for my BTS collection!!
Love this new addition to my growing A4 binder/myUniverse collection! I really like that the A4 myUniverse binders also come with a photocard display window, like the prior A5 myUniverse binders, but unlike other A4 duo editions this version does not have an interchangable design on the spine :(
This binder is the ultimate for Army... It's not only beautiful but also really functional. I know you can get cheaper products, but the quality, the inclusions and the how it's absolutely personalised for BTS sold me. Thanks Cathy and the team for making great products for the fans!
These binders are such great quality - I wasn't sure what to expect when I ordered but they are incredible. They look so stunning, the light blue is gorgeous and I'm obsessed. Definitely recommended!
Not a collector but this binder is perfect for storing and organising my pobs from merch and album purchases all in one place. Great quality and aesthetic as well. ✨
The Prism Platinum Tarot (Bias Wrecker) Binder is an exceptional piece, offering both high-quality construction and a unique design. The binder's navy-like color gives it a sleek, sophisticated look, making it stand out in any collection. The material is durable and smooth to the touch, ensuring long-lasting protection for your tarot cards. A standout feature is the dust case, which adds an extra layer of protection, keeping your cards pristine. Additionally, the binder includes thoughtful inclusions like card dividers and extra pockets, enhancing its practicality. Overall, it's a beautifully designed and highly functional storage solution for any tarot enthusiast.
These are my first Prism Platinum binders and I have to say, I’m highly impressed by the quality! From aesthetics of the actual binders to the packaging, it’s definitely worth investing in. It makes the process of collection all the more fun! :)
The quality of these binders is incredible! They’re sturdy and keep all the pages well-protected. Will definitely buy more as my pc collection gets bigger
The Tarot Series binder is the binder of dreams! It's sturdy, solid, the backboards are awesome and the binder shield is perfect to protect your sleeves and PCs when stored upright. I'm so glad I bought this on release day and I have the peace of mind that my binders are safe in this beautiful storage.
first off the ONLY reason I rate this as 4 stars instead of 5 is because its so big! So much bigger than I thought it would be and doesn't fit on any shelves I have. The one it's sitting on has nothing above it so there is space. However with that being said I still absolutely love this, it's my first ever duo binder and it looks absolutely stunning in person and the quality feels amazing and it feels STURDY in or outside of the outer box. I don't feel any worry when it comes to my pcs because I'm very confident that they're safe. The holo designs and the little cut outs are such a cute little touch. Definitely love this binder for sure, I just wish it was a tad shorter in height. <3 Still recommend tho!
