Nichigan Original Building Blocks 1 box, 100 pieces 3-box set, 300 pieces total. You can stack them to build towers or play dominoes. From simple shapes, you can play endlessly with your imagination. They were also used as counters. 1 piece: 9 x 3 x 1 cm Arranging 3 pieces creates a square. Since each side is a multiple of 3, they stack perfectly, offering the fun of endless stacking. Similar to Kapla blocks, but the precision of each piece is different, and the fact that they stack in multiples of 3 is the key. In the 5th photo, there are about a dozen pieces with stains from spilled barley tea, but they are generally clean. Because they are simple, you can play with them for a long time. Thank you.
