Uniconvex Yunzi Stones

Description

These Yunzi stones are of high quality, and are easy to hold and place on the board, making a satisfying clack. They are smooth, so don’t damage the board, and slide well over each other in the bowl.

They are uniconvex in shape (flat on one side, curved on the other), and measure 21mm across, and are 6mm thick in the middle.

Note: there has been some concern about Yunzi stones being contaminated with lead. These have been personally tested by me, and have been found to not be contaminated.
