About Single - A4 myCOLLECTION Binder
The Single size is one of three sizes available in the Custom A4 myCOLLECTION Binder range. It is the smallest in size and can fit up to x45 single-sided sheets of our Custom A4 9-Pocket Photocard Pages, which holds up to 405 photocards in total.
The custom A4 4-D ring binder is constructed with tough premium board core equipped with a dual magnet clasp. The 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 from our archival-safe Custom A4 Pocket Pages.

"It's the perfect way to upgrade from a hobby collector to a full fledged full set collector; from the backboard to protect the pages from bending to the Binder Shield that keeps the pages in place when they're stored upright - this set has it all!

Why myCOLLECTION is made like no other
Made to safely hold more
Big collections shouldn’t require making big compromises. Our Single A4 binder has been carefully sized to fit up to 405 photocards while staying sturdy, protective and easy to use, so you get the most storage possible without it becoming too heavy to handle or flimsy to trust.
Made to fit everything
From posters to sticker sheets, kpop collections go well beyond photocards. Unlike zip binders or collect books, our binders have no fixed pages to give you true flexibility to store and organise everything your collection may include. With over ten available Custom A4 Pocket Pages to choose from, there's a home for every odd inclusion.
Made for lasting protection
Generic office folders weren’t made for collecting. Our binders are engineered inside out for complete long-term protection, beginning with premium materials and finishing with our protective binder accessories included with every binder.

Beautiful design, i love the cutouts on the protective cover and the art design in the folder
It's my first time ordering from them. The album binders are really sturdy and they have a lot of space. The designs are also really beautiful with the holographic foil.
![Customer photo review of [PRE-ORDER] Part I - Astro - Midnight - Single - A4 myCOLLECTION Binder](http://images.loox.io/uploads/2026/3/24/Ere7lSyiM_mid.jpg)
Absolutely LOVE LOVE LOVE!! The quality is something I’ve never seen before. Best binder I’ve ever owned. Worth every dollar.
[PRE-ORDER] Part I - Astro - Midnight - Single - A4 myCOLLECTION Binder
I'm totally in love with this A4 Binder!
Heavy duty set. I love it!!!
Perfect for my collection! 100% recommend
I absolutely love it. The binder looks gorgeous and it arrived safely. Thank you so much. I am going to save up for my next beautiful binder. 🩷
Love this collection of design.
Love the design and it has really made my collection complete. Love love love! ❤️❤️
I’m so happy I’ve been looking for a good binder the material is amazing I love the size of it, I was gonna get the black one but got sold out! 🥹 I’ll be waiting for it to be restock again! xx
I loved it so much. As soon as I got it, I immediately moved almost all my collection to it, I do need to get more pages for it, but that's a future plan :) It's so pretty in person as well 💜💜
Great size and very handy, just wish you could receive the duo display case on request when you get one as I’ve had to get two individually as the duos are always sold out but they’re fine to stand individually next to each other
This is such a beautiful folder and I love it for my photocards and very protective as well. The packaging was amazing and can tell a lot of care went into it to it!!
Finally got the matching set and I love it — the case is amazing and my cards all feel protected/secure in it
Amazing quality! 💖
To start with, yes this is a ot of money for a binder, but I've had it for about a month now and I have no regrets. I really have not seen anything else available that compares to this and given it is a bit of a niche premium product I can see why it costs this much. It looks really pretty with the holo, and the astro design works particularly well I think for a SHINee collection. I really like that it's very minimal in terms of the branding. I use this mainly for my postcards and other items, so the majority of things in here aren't sleeved, but I have put some things in back to back which works fine. There are 49 pages in here, a few are still empty, but I could still add a few more when needed. The binder shield works well to keep everything in place, although the pages tend to puff out a bit as it's not full, I'm not too concerned. It is big and quite heavy, and sometimes a little bit of an effort to get it back into the case, but I love that the case means it stands up on its own and it also protects it. The foam-lined box that it came in is also very sturdy and is handy for storing things too. Overall I'm really happy with this purchase and would definitely buy a second one if there's a similar design available when I need it.
I love the binder so much, the design is beautiful and it’s such good quality! I’m definitely very happy with this purchase!!
These binders are just so pretty!!!! really make your collect so glamourous and well protected!!!
These binders are so great. Very strong and just such great quality. I will say because of the surface the black one leave finger prints so if you don't like that i would suggest the white version.
I am so in love with the intricate decals and the premium quality of the binder. Ngl, it’s a little heavy and not great if you wanna bring it around to flex. But prefect if you are looking to store it at home in a nice comfortable spot. Material is great but dents a little easily so ensure you place it on a flat surface when you are binding your pcs!
Beautifully constructed and you can really feel the quality. The included front and back protective boards and binder protector are consciously designed and gives the option of storing the binder upright without the insides sagging. Though the price may get you to second guess a purchase, I think it's worth it!
it's so cute!!! I love it!! I just started collecting and it's perfect!
Such a beautiful design u had to get the white version. I love that the designs work seamlessly together even if it’s black and white. The binder is really sturdy and spacious. Great for anyone wanting to expand their collection and have more photo cards on one page.
The new black A4 binder is absolutely beautiful!! The holographic design and the thick quality of the binder is everything I need to house my OT7 BTS inclusions. I love that the binder has its own protection box and the holds up perfectly vertical. 10/10
This binder is beautiful and solid, and perfect to store your precious collections and display, knowing everything is well-stored and protected inside. Even the protective shipping box it arrives in is solid and useful.
Even opening the box to get this felt like a premium experience. All the details are so well considered, and it feels like a real way to honour and cherish my photocards. Very impressed!
Beautiful. Amazing quality.
Beautiful. Amazing quality.
These binders are both beautiful and functional. They’re sturdy (I’ve dropped one a few times by accident) and have a lock on the rings to secure the pages. I use it quite a lot to make sure my card pages aren’t flopping around. I can imagine myself having a shelf full of them. I hope they come out with more designs to continue the spine art.
I had to pick this one up after I got my duo binder set because they are just too beautiful! :)
Absolutely love it! It arrived in extremely protective packaging and was amazing to unbox. Definitely love the ability to stand the binder upright without damaging the contents of the binder.
I am absolutely in love with my Astro binder!! It’s beautiful! I love that I have so much space to display all my PCs and signed postcards. Thank you Prism Platinum!
LOVE IT!
LOVE IT!
OMG! I couldn't believe how big this binder was. But, It is very sturdy and beautiful! I can't wait to use it!
Perfect size and quality
This binder is the best purchase I made. It looks so pretty and I can have all my collection on one place. Definitely recommend.
Very big and premium looking binder! Amazing sleek binder to showcase my collection. A binder fit for kings and queens!
