27-digit abacus, with a case for convenient portability. There are some peeling marks from stickers and some damage to the case. The beads in the center move smoothly, but the beads in the left 7 digits and the right 1 digit may not move well. (Please be sure to check the images) The left side is rarely used, so it may not be a problem for beginners to use. How about giving it a try? For those who understand that this is a home-stored item from an amateur (^^) - Type: Abacus - Number of digits: 27 - Accessories: With case Thank you for looking. #Abacus #Soroban #Abacus #Lessons #Calculation #Cover #Case
