★ WHY WE MADE IT
The inner sleeve we wished existed.
We collected for years before starting kkumi, and every "premium" sleeve felt like a compromise. Either too loose, too cloudy, or smelled like a chemical factory.
So we made our own. A snug-fit inner sleeve cut to the sweet spot for standard photocards. Just enough room to slide in without forcing it, never enough to swim around.
PVC-free, acid-free, 100 microns of clear CPP. No haze, no smell, no curling at the corners. Just the sleeve we wanted.

does it fit?
A quick check across the most common photocard sizes. For oversized or unusual sets, see the full sleeve guide.
✦ WHAT'S IN THE PACK
What you actually get.
every pack hand-checked before it leaves the studio ✦
Yes — sized for standard 55 × 85mm photocards (most K-pop album cards). The inner gives you a small gap on each side — snug but not forced.
Japanese cards are usually 55 × 91mm — those will fit but a little tight; consider our Long Slim for those.
What's the difference between Slim and Premium Clear?
Slim is an inner sleeve (no flap, low-bulk) designed to go inside a separate outer sleeve. Premium Clear is an outer sleeve (with a flap) — protects against scratches, dust and moisture. Most collectors use both.
How do I know if it's genuinely PVC-free?
We test each batch ourselves and publish the supplier MSDS on request. Material is CPP (cast polypropylene), a totally different polymer family. You can tell by feel — no oily residue, no smell.
Can I double-sleeve with these inside a toploader?
Absolutely. Slim → Premium Clear outer → toploader is the gold-standard triple-stack for valuable cards. We do this with our own collection.
When will my order ship?
Within 24 hours from Melbourne, business days. Standard AusPost is 2-5 business days nationally.
What's your return policy?
30-day no-questions returns on unopened packs. Opened it and hate it? Message us — we'll usually sort something out anyway.
The kkumi promise.
If your sleeves arrive damaged, don't fit, smell weird, or you just decide you don't like them — message us. We'll make it right. Every pack, every order, every time.
