1. What does it mean?
탑꾸 shortens 탑로더 꾸미기. A top loader is a rigid holder for a card; decorating its exterior with stickers, borders, or charms lets fans style the display without necessarily changing the card itself.
Also written or said as tapkku
2. The nuance
This is a narrower craft term than 포꾸. A decorated holder does not automatically guarantee archival protection, so avoid treating the term as a materials-quality claim.
3. Examples
“탑꾸 색을 포토카드 배경에 맞췄어.”
I matched the top-loader decorations to the photocard's background.
“주말에 덕메랑 탑꾸하면서 놀았어.”
My fan friend and I hung out decorating top loaders over the weekend.
