The mug is made from BPA-free, durable acrylic material.
Design: The double-walled design is intended to facilitate rapid chilling of drinks without leaving condensation rings on surfaces. The handle is designed for a comfortable and secure grip.
Function: The mug can be placed in a freezer to allow the liquid between the layers to freeze, providing a long-lasting cooling effect for the beverage inside without diluting it like ice cubes would.
The mug is not safe for dishwasher or microwave use.
