Thank you for viewing! This is a wooden abacus (soroban) sold by BorneLund. ・Material: Wood ・Size: 30 x 34.5 x 11 cm Various types are sold by other manufacturers, but this one is made of natural materials and has good color. It's a popular item from BorneLund, often out of stock. My child has outgrown it, so I hope someone who is looking for one can make good use of it. I had it displayed in the children's room for about three years, but it wasn't used very often. There are no noticeable stains or scratches, but please be sure to check the photos. The coloring of the beads is also almost perfectly intact. Before listing, I cleaned it thoroughly and disinfected it with alcohol, but it is still a used item, so please refrain from purchasing if you are at all concerned. It is not an assembly type, so I plan to wrap it in cushioning material for shipping.
