If you’re someone who enjoys DIY crafts or collecting photocards, then top loaders probably aren’t new to you. But what exactly are they?

Top loaders are clear, hard plastic sleeves that open from the top. Originally made to protect trading cards—like K-pop photocards or anime-themed game cards—they’re strong and reliable, keeping your items safe from bending, dust, and scratches.

These days, top loaders have grown in popularity across fan communities—from K-pop and Webtoons to anime lovers. But they’re no longer just plain, protective sleeves. People now decorate them with stickers, keychain charms, whipped cream glue, and more—turning them into eye-catching mini photo frames full of personality. There’s no rule: you can decorate them however you like, in your own style.

In countries like Vietnam, Japan, Korea, and China, top loaders have become so popular that some cafés and studios even host workshops where fans can come together, decorate sleeves, and share their creations. It’s a fun and creative way to relax, relieve stress, and connect with friends.

If you haven’t tried decorating one yet—why not give it a go?
