This is a set of 4 clear file folders featuring illustrations of BT21 characters. I put them in a file immediately after receiving them and have stored them, but please refrain from purchasing if you are sensitive to minor imperfections due to amateur storage. I plan to ship them with only waterproof packaging. If you require cardboard reinforcement, etc., I will add the packaging cost, so please let me know in the comments. - Design: Clear file folders with illustrations of BT21 characters - Quantity: Set of 4 - Theme: Designs that include messages of gratitude - Brand: LINE FRIENDS Thank you for looking.
