- 100% Borosilicate Glass (odor-free, stain-free + clean tasting) 

- Real friction-fit bamboo lid (not leak-proof when tumbler is tipped)

- 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. All you need is to rinse them out under the tap after everyday use or shake in a jar of warm soapy water if you like. Every month or so, you can boil a pot of vinegar water mix and soak the straws for a few mins if you want a super thorough clean! Always let your bamboo straws dry fully. They dry very quickly!
