These are defective Shogi pieces produced during manufacturing. Would you like them for practicing engraved pieces? All the pieces have cracks, knots, size defects, and other imperfections. Please be aware that these are defective products before purchasing. The sizes are roughly shaped, but the accuracy is quite poor. The material is Chinese boxwood. There are 40 pieces. Some are thick, and some are thin. This is for the piece blanks only; no container is included.
