You don't want your wine glasses, martini stems, margarita bowls, and pilsner talls running around barefoot, do you? They leave footprints - sometimes indelible ones. So treat yourself and your party guests to some colorful stemware footwear. Our Flip Flop Stemware Coasters come four to a set, and each one's a different color so you can easily find your glass on a full table. And the nifty straps keep them firmly attached to the bottom of your glass when you wander and mingle. Flip Flop Stemware Coasters bring new meaning to the phrase "casual entertaining" and make a great hostess gift! Universally sized to fit most stemware, delicate to thick.
