Math blocks purchased a few years ago at elementary school. It seems they weren't used much. Blocks: 20 squares Storage case: 2 cases of 10 each 2 cases of 5 each Paper cards: 2 cards in units of 5 10 cards in units of 10 Names were written on with stickers. There are some sticker marks remaining on the paper cards, etc. (See photos) I would like to pack and ship them with the case lids open. 【Size】 Length: Approximately 18cm Width: Approximately 7cm I hope you will find them useful. ☆
