This is a listing for the building blocks of the Alphabet Abacus (alphabet abacus) from the Belgian toy manufacturer, "Classic World." There are 30 pieces in total. The abacus as a whole is large, and shipping costs are quite high, so I'm listing only the building blocks to make it more affordable. I think you can have fun playing with them in various ways, such as building blocks, dominoes, stringing beads, etc.! If you wish, I will include the wooden rods of the abacus for free. If you are willing to cover the additional shipping cost of +530 yen, I will create a dedicated page to sell the entire abacus. Please comment if you'd like this option. The abacus is designed to be disassembled. If you are interested in the exact size, etc., you can check it on Amazon or Rakuten, where it is sold.
