At Tumblers Galore we take great pride in the quality of tumblers we sell and the unique variety of designs we carry. Our tumblers are double-wall insulated, dishwasher (top shelf) and microwave safe, and come with a lifetime guarantee. Each tumbler is made with two layers of polycarbonate. The embroidered and monogram emblems are ultrasonically sealed between the two layers. Because they are double-wall insulated, your cold drinks will stay cold longer and your hot drinks will stay hot longer, and the outside surface of your tumbler will always be comfortable to the touch. With the clear-like-glass appearance, our tumblers and mugs are nice enough to have on a fancy table yet durable enough to be used outdoors, as they are virtually unbreakable. Choose from over 100 unique emblem designs or you may want to have a custom emblem made for your next event. Once you use our tumblers you'll never want to use a regular glass again!
