Part II - Astro + Wanderlust - Midnight Duo Edition - A4 myCOLLECTION Binder
Discover the ULTBIAS difference
Description
Astro & Wanderlust - Part II continues the story, settling deeper into the quiet magic that first enchanted. Astro slows into stillness: a crescent moon lingers in the sky, gesturing towards contemplation rather than change. In Wanderlust, curosity gives awy to quiet mastery with a graceful cat now perched on the moon's curve, resting in steady confidence. Together, they capture a stillness that feels both distant and familiar, wonder settling into something that stays.
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 together in one shared outer case.
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.

This is the 3rd Duo Binder that I have purchased since I found out about ULTBias. I am obsessed with them.

Always great quantity binders and supplies! A must have for collectors!
Part II - Astro + Wanderlust - Dream Duo Edition - A4 myCOLLECTION Binder
I loved it! It’s very nice and exactly what I needed. The only thing I didn't like was that it was sent in a much larger box.
Part II - Astro + Wanderlust - Midnight Duo Edition - A4 myCOLLECTION Binder
The duo case is very sturdy and attractive. The set came packaged in a gorgeous, strong outer protective box that I'm going to keep for storage.

As someone that has the original Astro duo, I’m glad to add this for my &Team collection. I like having the magnetic closure and tabs. It looks great next to the original.

I have been waiting over a year for these to come back in stock because no other binders compare! I love that the binders are carefully packaged to avoid any damage, and the new design is so pretty! I store my ateez ot8 photocard collections and inclusions in these binders and I love how everything fits so perfectly and safely. They were well worth the wait!

My reason for giving a less than perfect score is it doesn’t “fit” in with my previous binders. The binders are well made and shipping was…ok (box was opened cause only one piece of tape was used around the entire box, but the binder and outer box were thankfully unharmed.

I have a couple of the A4 Binders and well I really love pretty much all of them. From the design of the foiling to the sturdy shape and well pretty much everything in between. If I really had to pick something to nit pick at. The first binder that they did in the A4 series was slightly bigger than the ones they do now. I would have loved to see that same sir carry on into the newer A4 binders. That’s just me being picky though. I’m sure I’ll be buying more A4 binders in the future.
