I purchased this item many years ago, but I've been using it for storage. Since I rarely took things in and out, the condition is good. In the third photo, there are marks from the shape of a button on the inside. Approximate external dimensions: 23.7 x 17.3 x 2.5 cm (depth) It's large enough to hold an A5 notebook. I will ship via Nekopos (a Japanese delivery service).
