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.
- Ultra-Portable Profile: With a 350ml capacity, this tumbler is specifically designed to be "pocket-friendly." Its compact dimensions make it easy to carry in small handbags or jacket pockets, making it the ultimate travel companion for urban explorers.
