These flashcards support efficient learning. ☆ I'm selling unused flashcards, having purchased various types (2-packs and 3-packs) to organize by subject. ・ STAD (Kutsuwa Co., Ltd.) 70mm x 30mm, 80 sheets ・ WordCards (Nakabayashi Co., Ltd.) 70mm x 30mm, 81 sheets (+ red/green sheet) ・ WORD CARDS (Kyokuto) 80mm x 25mm, 81 sheets ・ Accessories: Card rings 25mm x 6 ☆ STAD has a black dot on the cover from the time of purchase. ☆ The red/green sheet from Nakabayashi doesn't look great currently, but it's due to the protective sheet being wrinkled. Please peel off the sheet before use. ☆ The card rings are from Daiso (12-pack), and I used 6 of them. I'll include them if you'd like. ☆ There are minor scratches and scuffs on all items, likely from storage. ☆ Items will be packaged in a waterproof vinyl bag. ☆ Shipping is planned via Yu-packet Post Mini. Thank you for looking.
