This printed wrap-around design is sealed between the tumbler walls. Tervis tumblers feature double-wall insulated construction that keeps drinks hot or cold longer and reduces condensation to prevent rings on your table. Strong, impact resistant BPA-free material means these tumblers can take a tumble without shattering and won't retain tastes or odors. Tumbler also comes with an easy-to-clean BPA-free travel lid. Most tumblers are microwave, freezer and dishwasher safe for no-worry convenience and fit most cup holders.
