IJ Unbreakable Glass Tumblers, 10-Pack, 250ml, Microwave and Dishwasher Safe, Made in Japan,

The Crush Tumbler series features Japanese-made glasses that won't break even after being dropped 1000 times. Compared to ceramic or glass tumblers, they have lower thermal conductivity and better heat retention. They are dishwasher, microwave, and alcohol-safe for easy cleaning.

Suitable for a variety of beverages including coffee, juice, highballs, and beer, they add a stylish touch to your table. With a heat resistance of 100°C, they can also be used like a mug for enjoying cup soups, or you can add ice and pour in hot coffee to enjoy freshly brewed iced coffee.

These glasses are a convenient size for everyone, from children to adults. Suitable for both men and women, they make a great wedding gift, birthday present, or Mother's Day or Father's Day gift.

Available in three sizes: a large 400ml, a small 250ml, and an even smaller 205ml. They are versatile enough for various uses, from beer glasses and rock glasses to bathroom cups for brushing teeth.

Capacity: 250ml Size: Diameter 8cm x Height 9cm Material: Tritan (a reusable plastic that is as transparent as glass. It is the same material used for baby bottles.) It can be used in a microwave oven, but there is a risk of deformation, so please read the instructions carefully before use. *Due to the transition period of the instruction manual, it may say that it is not microwave-safe, but it can be used in a microwave oven regardless of what is written in the instruction manual.
