These are natural, multi-colored "ohajiki" (Japanese game pieces) made by carving out shells. Unlike glass ones, they have a slightly different thickness and beautiful patterns. You'll find them if you search online, but they are hard to come by. High-quality ones have subtle variations even within the same color, which fosters a rich sense of color. Some of the game pieces have chipped edges, which adds to their charm, so please enjoy them as such. - Color: Multicolor - Shape: Round - Material: Clam shell - Size: Approximately 2 cm in diameter - Design: Striped pattern Thank you for looking.
