Key Benefits

Medical-Grade 316 Stainless Steel:** The interior features a seamless SUS 316 stainless steel liner. This high-grade material is superior to standard 304 steel, offering enhanced resistance to corrosion from acidic coffee or tea and ensuring a pure, metallic-free taste with every sip.

6-Hour Thermal Performance:** Engineered for the busy professional, this tumbler provides up to 6 hours of reliable temperature retention. Enjoy your beverage exactly how you like it, from the first sip of your morning commute to your mid-day break.

Exquisite Piano Paint Finish:** Inspired by classic Italian design, the exterior boasts a high-gloss piano lacquer finish. This not only provides a sophisticated, retro look but also offers a comfortable, non-slip grip that is highly resistant to scratches and everyday wear.

360° Leak-Proof Security:** Travel with total peace of mind. The combination of a precision spiral screw-top and a high-quality food-grade silicone sealing ring creates a vacuum-tight closure, making it completely leak-proof even when tossed into a crowded bag.
