Building blocks. These are wooden toys from KAWAI, Kawai Musical Instruments. They have been played with by a child, so there are stains and signs of use. There are some stains as shown in the photos. I think they can still be used, so I will sell them at a low price to those who understand everything. The box is also tattered as shown in the photos. Please let me know if you don't need it. These are used items, so please refrain from purchasing if you are looking for perfect or beautiful items. Please forgive any oversights as they are stored and inspected by amateurs. We do not accept refunds, returns, or complaints after purchase. #1.5 years old and up
