⭐︎We ship within 24 hours⭐︎ Thank you for viewing. This is a case made for a 23cm abacus. There are marks from where a name tag (iron-on type) was attached to the back. I used this for about a year while attending abacus lessons. This is handmade by an amateur, so please refrain from purchasing if you are concerned about minor details. Home-cleaned. We plan to ship via Yu-Packet Post (anonymous delivery).
