Sansu Set A - Japanese Standard For the academic ability of all children. Purchased upon entering elementary school. This is what my child used in class. There are traces of name stickers having been peeled off, and areas where the name has been blacked out with a marker. Items that were used frequently show signs of wear. I believe everything that was included at the time of purchase is present. The lid of the abacus container is broken, but it can still be opened and closed. Suitable for elementary school students, of course, but also for pre-school learning. This is a used item, so please understand this before purchasing. Thank you.
