Good to know

Borosilicate glass
Borosilicate glass is heat-resistant and is therefore particularly suitable for drinkware used for both hot and cold beverages. In the RETUMBLER®-NIZZA Glass, the material combines a clear, premium appearance with convenient everyday practicality. The transparent design keeps both the drink and its fill level visible. This makes the mug a modern alternative to thermal mugs made from opaque materials.
Double-walled construction
The two glass walls of the RETUMBLER®-NIZZA Glass support temperature insulation. Hot drinks remain warm for up to 2 hours, while cold drinks stay cool for up to 8 hours. At the same time, the construction helps make the mug comfortable to hold.
