This is a set of two 23-digit abacuses. They were used by a family member and have name stickers attached (the white parts in the images). Also, one of the abacuses has many grade achievement stickers on it. The other abacus does not have grade stickers. Please check the images. Cases for the abacuses are also included. The cases have names written inside, and one of them shows some signs of use on the inside, so please consider it as a bonus.
