These are beautiful large mugs, approximately 4" tall iridescent & translucent with colors that vary with angle, light, etc. I cannot find this specific cups so do not know age or if vintage? NOT microwave or dishwasher safe so wonder if older? Would be pretty holding a small bouquet of flowers or container as well as cup. Ample size mugs, iridescent, translucent, colorful, unique, decoration, drink ware.
