Whaline Drinking Glasses

While the glass tumblers are dishwasher safe, we recommend hand-washing the bamboo lids to prevent warping or mold growth. The glass straws should also be hand-washed with the included brushes to ensure they remain completely clean.

The bamboo lids feature a silicone gasket that provides a snug, secure fit for everyday use. However, they are designed for sipping and preventing splashes rather than being fully leak-proof, so you should avoid tossing them in a bag.

Each glass holds 16 ounces, which is the standard size for most iced coffee drinks or cocktails. This capacity leaves enough room at the top to comfortably add ice without the liquid overflowing.

The included glass straws are made from high-quality, shatter-resistant borosilicate glass. While they are stronger than standard glassware, they should still be handled with care and kept away from hard surfaces to prevent chipping or cracking.

These glasses are primarily designed for cold beverages like iced coffee, smoothies, and cocktails. We do not recommend using them for boiling hot liquids, as the glass is not tempered for extreme thermal shock.
