Price listed is for three glass stones. These are jet black navettes that measure approximately 15mm by 7mm. They are etched with an ''X'' and have very small swirl patterns within the etched portion. The tops and backs are both smooth and flat. These have a square recess in the middle. Though the recesses are square, they will fit a 14pp (6ss, 2mm-2.10mm) point back stone. The size and shape varies slightly from stone to stone.
