Born from Zojirushi's 100-year history of perfecting Japanese home appliances, this vacuum mug was created for a modern life that demands reliability. While other mugs fail, our engineers in Osaka selected 18/8 stainless steel and a patented vacuum insulation system to solve the problem of lukewarm drinks. Every component is tested in our certified Japanese factories, adhering to strict JIS standards. The result isn't just a mug; it's the top-ranked insulated drinkware in its category on Japanese review sites, trusted by millions who refuse to compromise on their daily ritual.

The Zojirushi 480ml Pink Stainless Steel Vacuum Mug is constructed primarily from high-quality 18/8 stainless steel, which forms the inner and outer layers of the double-wall vacuum insulation system. This stainless steel is chosen for its durability, corrosion resistance, and non-reactive properties, ensuring that beverages maintain their pure taste without metallic contamination. The vacuum-sealed space between the walls eliminates heat transfer by convection and conduction, providing superior thermal retention to keep drinks hot or cold for extended periods. Additionally, the interior features a non-stick, scratch-resistant coating, often made from a food-safe fluorocarbon polymer, which prevents residue buildup and simplifies cleaning. The lid components, including the gasket and seal, are typically composed of BPA-free silicone or similar elastomers, ensuring a leak-proof closure while being safe for contact with liquids. These materials collectively offer benefits such as exceptional insulation performance, hygienic maintenance, and long-lasting reliability, making the mug ideal for daily use in various settings.
