Always keep track of your wine glass! No need to worry how to identify your glasses anymore. The wine glass marker's ink stays on for the entire party and washes off easily with a sponge or in the dishwasher. Besides wine glasses, they are also a great way to label glass and glazed ceramic serving platters or write directly on wine bottles. Forget about the jangling wine charms tangled in the drawer, and get a set of wine glass markers instead.
