nice starter set [SEP] stones were smaller than expected but i can still work with them i might have to find a larger sacral belly stone to replace this one other than that these were all very nice just the right amount of smoothness and grip nicely organized and matched sizes i like the way they were all labeled upon receipt i especially liked the bonus stones edit this is a wonderful company i will definitely buy some specialty stones from them in the near future they read my review and offered to replace my sacral stone cannot get better customer service than that
