Silver Buffalo Sanrio Hello Kitty Glass Jar Tumbler

The bamboo lid features a silicone gasket to create a snug, secure fit, but it is not completely leak-proof. It is designed to prevent splashes rather than to be tossed loosely into a bag.

This tumbler is primarily designed for cold beverages like iced coffee, tea, or water. While the glass is durable, it is not borosilicate glass, so it is best to avoid boiling or extremely hot liquids to prevent thermal shock.

The design is printed directly onto the glass surface. To preserve the artwork and keep it from fading or peeling, we recommend hand-washing the tumbler rather than using a dishwasher.

Bamboo is a natural material that can warp or mold if left soaking in water. After washing, wipe the lid dry immediately and let it air dry completely before storing it on the jar.

The included glass straw is made of standard glass, which is durable for everyday use but can break if dropped on hard surfaces. Handle it with the same care you would use for a glass cup.
