Stainless Steel Double-Wall Tumbler - 300ml Gold-Plated

The Art of the Perfect Chill Born in Tsubame, Japan — the legendary capital of Japanese metalworking — this premium double-wall tumbler redefines what a cold drink can feel like. Silver on the outside. Gold on the inside. Cool to the touch, always. Stay Colder, Longer — Even on the Hottest Days Engineered with advanced double-wall thermal insulation, this tumbler keeps your drinks icier and more refreshing for longer — far beyond what a standard glass or single-wall cup can achieve. The anti-condensation outer wall stays completely sweat-free, so your hands stay dry and your table stays spotless. Whether it's a chilled sake on a summer evening, an ice-cold craft beer, or a whisky on the rocks — every sip is as cold and crisp as the first. 24K Gold-Plated Interior — Where Luxury Meets Purity The inner surface is meticulously coated with pure 24K gold — not for show alone, but for science. Gold is chemically inert, meaning it creates a completely neutral barrier between the metal and your drink. No metallic taste. No odor. Just the pure, unadulterated flavor of your finest sake, whisky, or craft beer, delivered with a remarkably smooth mouthfeel that only gold can provide. This is luxury with a purpose.
