Case size: Width 7cm, Total length 10cm. This is the type where you insert from the left side (see the arrow in photo 3). If any parts come off, please reattach them with glue. I have a cat. I made this in a room where the cat isn't allowed, so I don't think there will be much cat hair on the product itself, but there is a possibility. I will remove any visible dust before shipping, but some may still get attached. Please refrain from purchasing if you are looking for a perfect product. #UsasanWhipDeco Trading card, trading card deco, hard case Oshi-katsu, Ota-katsu, Kpop, Korean, light blue, heart Instant purchase is OK ⭕️
