Silicone sleeves make the glass perfect for outdoor use.

– Real friction-fit bamboo lid (not leak-proof when the tumbler is tipped)
– All parts are BPA/BPS Free
– Glass tumbler is top-rack dishwasher safe (bamboo lid/straw and silicone sleeve are NOT dishwasher safe). Do not microwave, do not freeze.

Removable silicone sleeve, bamboo lid and bamboo straw can be customized with a laser engraving machine.

Caring for bamboo straw/lid to help prevent mold:
1. Rinse out under water after everyday use or shake in warm soapy water. Every month or so, you can boil a pot of vinegar water mix and soak the straws for a few mins. Let fully dry.
2. Dry them flat so that water does not collect at the bottom.
3. Store your straws in a well-ventilated place, and never in air-tight containers
