This 24oz custom designed tumbler is made by Tervis. Each custom Lug Tervis tumbler features 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. Each tumbler also comes with an easy-to-clean BPA-free travel lid.
