Wine Glass Writers are markers for your glasses, both stemware and tumblers. Write your name; get creative with a design. (Great for writing on wine bottles given as gifts.) No more jangling wine charms tangled in the drawer. No need to worry how to identify tumblers and other stemless glasses. Stays on for the party and washes off with a sponge or in the dishwasher. Non-toxic, patented ink. Also writes on leaded crystal, plastic and glazed ceramics. Pack includes three pens. Colors: metallic silver, metallic gold and metallic green.
