The Glass Original Bottle is made from high-quality, borosilicate glass. While it is durable and break-resistant, we urge you to treat it carefully and use caution as it is still made from glass. If your glass bottle breaks or cracks, dispose of it right away.

The Glass Original Bottle is made with zero plastic. The bottle is made from high-quality borosilicate glass, the sleeve is made from food-grade silicone, and the lid is made from 18/8 stainless steel with a food-grade silicone gasket.

The bottle can be used for hot drinks, but we urge you to use caution with hot liquids and allow the drink to cool to a drinkable temperature before using. Ensure the lid is fully tightened after filling with hot liquids.

The Glass Original Bottle is freezer-safe when empty. Do not freeze with liquids inside.

No, we don’t recommend you put your Glass Original Bottle in the microwave.

No, we don’t recommend using carbonated drinks in your Glass Original Bottle, as pressure buildup can cause the lid to pop off.

The lid is made from 18/8 stainless steel with a removable food-grade silicone gasket for easy cleaning. The silicone gasket covers the stainless steel lid, so the lid does not impart any metallic taste.

The Glass Original Bottle is fully dishwasher safe, including the silicone sleeve and lid. For a deeper clean, we recommend hand washing with warm, soapy water and using our Bottle Brush to get into the small mouth opening. Let the bottle dry with the lid removed. Do not use cleaners containing bleach, chlorine, abrasives and/or other harsh chemicals.

It is not necessary to remove the silicone sleeve for dishwashing. If you need to remove the sleeve, carefully twist and pull it off.

Yes, you can bring your bottle through airport security. Be sure to remove all liquids before bringing it through security.
