Double wall borosilicate glass bottle

This double wall borosilicate glass bottle can hold both hot and cold drinks. Unlike regular glass, this will not crack under extreme temperature changes. On the inside is a removable tea infuser/strainer to help infuse the water with your favourite fruit flavour or tea. The top of the lid has a built-in LED touch thermometer that shows the current temperature of the liquid inside. Never burn your lips on hot tea again with this bottle. Take this bottle with you wherever you go. It is leakproof, so you will have no trouble carrying it in your bag. 1 CR2032 battery included. Capacity: 390ml. Laser engraving is not possible on borosilicate glass.
