Leak-Proof Factory-Direct Trendy Stainless Steel Water Bottle for Daily Commute

Stainless steel insulated cup is a drinking water container made of food grade stainless steel (304) as the core material of the inner liner, combined with vacuum insulation technology. Its core structure lies in the vacuum state between the double-layer stainless steel walls, effectively blocking the three main modes of heat transfer: heat conduction, heat convection, and heat radiation.

Excellent insulation and cooling performance

Vacuum insulation significantly slows down the heat exchange rate. High quality insulated cups can keep hot drinks warm for 6-12 hours or more, and cold drinks cool for 12-24 hours or more, meeting the needs of all day drinking.

Safe, Healthy and Durable

The inner liner is made of 304 food-grade stainless steel and does not contain harmful substances such as BPA. It has strong corrosion resistance and is not easy to rust. The stainless steel material is sturdy and resistant to drops, ensuring a long service life.
