Instant purchase OK! These are abacuses from a math set. The box in the first photo is not included. ⭐ I have checked the number of pieces several times, but please understand if there are any oversights. ⭐ Please consider purchasing, understanding that some items may have sticky residue from removed name stickers. ⭐ Preparation for elementary school is starting early in some areas! Even if you buy them for school use, the usage period is shorter than you think, so how about these if you're okay with used items, if your child has lost a piece and you're looking for a single one? ⭐ Used, home-stored items. ⭐ Please purchase after you are satisfied with the condition.
