Astro & Wanderlust - Part I is where the story begins. In Astro, ever-shifting moon phases trace a new celestial rhythm, guiding the journey forward. In Wanderlust, the bunny once dreaming now takes flight, hope and courage carrying it beyond the familiar. Together, they form a world of soft magic, where discovery feels as meaningful as the destination.
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.
Care Note
To preserve our myCOLLECTION binders, store away from direct sunlight in a cool, dark space.

"The best purchase I’ve made"
"I’m a novice collector that let a lot of my postcards and photo cards pile up in some box, but keep them in these binders are the best decision/purchase I’ve made. The binders a beautiful and they’re excellent quality, I no longer worry about my collection being damaged in the box I kept them in anymore. I just love to flip through them! Would recommend these binders to anyone who loves to collect!"

Customer Reviews
Overall rating: 5.0 / 5 from 40 reviews.
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
Perfect for my collection! 100% recommend
Love this collection of design.
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!!!
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!
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
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.
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!
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
Very big and premium looking binder! Amazing sleek binder to showcase my collection. A binder fit for kings and queens!
Exactly as advertised, packed so safely for shipping, so beautiful it's going to look great displaying my collection. feel safe knowing my pcs are safe and sound in thete
Beautiful!! Absolute love it.
Absolutely love! The quality is amazing! I’m going to slowly replace my entire collection with prism platinum!
I love this binder! This is my second one of these after upgrading to the A5 size and the quality is amazing. They also look great on my shelves with the holographic accents. I love how even though the designs aren't exactly alike, they flow together on the spines of the binders. Such a cute detail!
Hermoso, sus binder son de excelente calidad, 100% recomendado
This binder is so deluxe down to the great packaging! It’s beautiful and sturdy and the accessories it comes with makes everything that much more stable! I absolutely love it!
I'm really in love with that A4 Binder! It's just perfect
Love it
Genuinely love this binder so much! Fits my collection perfectly and the cards look so clear! The design is gorgeous and I’ve had so many friends ask where they can get one for their collections! Will definitely buy another one soon 🤍🖤
This A4 binder couldn’t be more beautiful! I’m a new collector & couldn’t be happier with the quality. I can’t recommend any of their products enough!
So pretty
Binder is beautiful!! My cards are nicely displayed and protected!
Such a beautiful binder. So happy with my purchase.
Perfect upgrade for my collection 💜💜💜
Packaging was neat and beautiful and the product was a little larger than I expected but so worth it. Such high quality!
Beautifully crafted
