My mandala stones are hand painted and protected with two coats of matt vanish. They are not suitable for outdoor use however. The smooth surface of these stones is the perfect surface to paint on and I can think of no better subject than beautiful, colourful mandalas. This mandala is about 2.5 wide and approximately 1 deep. There is no mass production. They are ALL one of a kind. International shipping now available. Please be sure to read my Shop Policies.
