Made in West Germany. These glass stones are hand crafted using vintage style tools. Each stone is hand pressed with a smooth slightly domed side through which you can see a detailed intaglio image of an Owl molded into the back of the stone. As a handworked stone, each piece will vary slightly in size, color and may have small imperfections. These items have not been tested for lead or cadmium and should not be used in items intended for use by children.
