This is something I used in elementary school. I only used it for a few days. The case shows slight signs of use, but the abacus itself is clean and in excellent condition. It functions well. *My name is engraved on it, but I haven't included that information due to privacy concerns. Please be aware of this before purchasing. Due to the low price, which is essentially the shipping cost plus fees, I cannot offer any discounts. 【Important Notes and Apologies】 *I travel frequently for work, so there may be delays in responding to messages or shipping items. I sincerely apologize for any inconvenience, and I appreciate your understanding. *Regardless of any comments, the first person to complete the purchase process will be given priority.
