Safe Material: Use non-reactive and lightweight food grade 18/8 stainless steel, no peculiar smell and BPA-free, easy to clean and good for your health. All materials in contact with water are FDA GRAS compliant.
Easy to Carry: The humanized shape with lower narrowing not only ensures the capacity but also fits most cup holders for automobiles. And the tumbler body is comfortable for your hands too.
Good Sealing and Convenient Drinking: The lid seals well with the silicone O ring and flip cap for leak-free carrying. The big drinking mouth allows you to choose a direct water flow or a straw-drinking.
