This Lovely Eye Catching Coaster Set of 6 has a beautiful lime green background with a black boarder.  It highlights two Mother of Pearl Inlaid Geisha Girls walking with flowers. The coasters measure 4" square. The box measures 4 3/4" square. It is made of hard plastic. There is a #6 on the bottom of the box. The set is used and does show some wear but overall the set is in very good condition. See Photos.
