The "Mini" Stainless Mug is ultra-lightweight and compact. It features a one-piece lid with a seamless structural design, allowing for easy cleaning without the need for disassembly. Cute and stylish, it can be taken wherever you go.
Zojirushi's Stainless Mug has a stainless steel vacuum insulation that keeps beverages hot or cold for hours! This bottle is designed to drink directly out of the mug, made with a rounded sip area. It features an easy-to-clean nonstick interior with a leak-proof*, gasket-free one-piece lid (*When used properly according to the instruction manual). A special manufacturing technique was used to make the body ultra-lightweight and compact. 1-5/8" (4 cm) wide mouth opening accommodates full-size ice cubes and is easy to fill. Made of BPA-free plastic and stainless steel.
Vacuum means the air between the outer and inner layers of stainless steel has been removed to create a vacuum insulation. It blocks heat from transferring through air (conduction). Zojirushi vacuum insulation also features a copper or aluminum layer tightly wrapped around the outside of the inner stainless steel layer. This copper or aluminum layer reflects heat (radiation), further minimizing the temperature change of your drink. Lastly, heat is blocked from escaping through the opening (convection) with a tightly closed lid.
