This slim double wall tumbler is clear like glass but made of resin, so it will not break if dropped. You can stack the glasses or lay them on their side without worrying about breakage.
The double wall structure keeps heat from passing through, and it also keeps cold drinks cold with very little condensation on the outside. The rim is rounded for a smooth feel on the lips.
The glass can go in the microwave for reheating drinks only, and it is dishwasher safe. Bleach can be used, so stains and leftover color wash out cleanly. It measures 13.1 x 8.8 x 8.8 cm (5.2 x 3.5 x 3.5 in) and weighs 135 g (4.8 oz / 0.30 lb). Made in Japan by Akebono Sangyo of Tsubame, Niigata, a maker of plastic kitchenware.
