Fabulous set of old coasters, 7 coasters with lovely mosaic centers and shiny gold finish borders over a gold tone metal assumed to be aluminum. Several have the original labels on the bottom "Modern Mosaic by Styson Art Products Japan". Each coaster is 4" across, with an approximate 2 & 3/8" center for your drink. All are in very good condition with only mild wear from age. Price is for the set, not for sale individually.
