Tomoe Soroban (Abacus) - 23 Digits This is a very old item. It was used, so there are some scratches. There is a smell from being stored away. For those who don't mind. ※ The cover is dirty. Also, the name has been blacked out with a marker. If you don't need the cover, please let me know. ✂︎--------- Soroban (Abacus) Abacus Calculation Lessons Arithmetic Calculation School Tomoe Soroban TOMOE Retro Interior Showa (Era)
