Sleeve Guide
PHOTOCARD SLEEVE SIZES FOR K-POP COLLECTORS
Every sleeve (and all of our other products) in our range has a fun K-pop song inspired name! We'll leave it to you to figure out which ones (try and see if you can recognise them all!) ~
First, a quick note: the sizes themselves aren't something we invented. Sleeves have always been sized around the cards and you'll find they're pretty much universal across different stores. What we did decide to do, was name each size after the job it does, and then name that job after a song.

A note on PVC
There's PVC, and there's PVC. Rigid PVC (99% of toploaders) is stable, inert, and generally safe for long-term storage. That said, PVC-Free toploaders are something we care about and are actively looking into. In the meantime, we still recommend sleeving your cards before loading them, because while the risk is low, it isn't zero.
Soft PVC is the one to watch out for. The plasticisers in soft PVC can migrate and damage finishes (like your cards) over time. Every Kkumi sleeve is 100% cast polypropylene, which means they're 100% PVC-free, and 100% acid-free.
