Change Glass Straw Insulation Mug 680ml, Colors Available

This tumbler is crafted from premium, double-walled stainless steel. A "vacuum space" between the inner and outer walls prevents the transfer of heat or cold, while a foil lining on the inner wall reflects heat back inside, ensuring a stable internal temperature and excellent cold retention.

The inner cover can be used as a direct drink or straw to drink water, with a scented tea net, and the outer cover can be used as a small tea cover
