Great sizing kit that came much faster than I expected considering it was shipped internationally. Very high quality stones and an excellent show of what I can expect when I order the size I want. Would absolutely recommend if you need to see what size stones you need, but also to get a glimpse of the incredible quality you can expect when you do order a set.

As the AGA Chapter Representative of the San Diego Go Club, I have had members of the club ask me about the best sized slate and shell go stones to buy. This inspired me to buy your Go stone thickness sample set. Now I can let them try out the various sized Go stones before buying. The set was impeccable and well displayed with the corresponding measurements. And they sound great when played on my thick Kaya board.

This was a good sampler set. It helped me choose which stone size was most comfortable. I settled on size 32 (30 felt too light).
