Elevate your hydration ritual with the T-TWELVE Cloud Vein Miracle Series Insulated Tumbler — where ancient Eastern philosophy meets modern engineering. Inspired by the flow of natural marble veins, each tumbler features a one-of-a-kind swirling pattern that transforms a daily essential into a wearable statement piece.
Superior Thermal Performance
Built with a double-wall vacuum insulation system, this 740ml tumbler keeps your beverages hot for up to 12 hours and cold for up to 24 hours. Whether you're sipping hot tea on a winter morning or enjoying iced lemon water at the gym, your drink stays at the perfect temperature from dawn to dusk.
Medical-Grade 316 Stainless Steel Interior
Unlike ordinary bottles that use 304 stainless steel, the Cloud Vein Miracle Series features a SUS 316 medical-grade stainless steel inner wall. This premium material is resistant to corrosion from acidic beverages — safely hold fruit juice, tea, milk, cola, and lemon water without any metallic aftertaste or chemical leaching. BPA-free and phthalate-free for peace of mind.
Wear It Your Way
The included adjustable braided shoulder strap transforms this tumbler into a hands-free crossbody accessory. Wear it over your shoulder, carry it by hand, or hang it from your bag — the reinforced quick-release clip system ensures a secure fit wherever your day takes you.
Built for Real Life
360° Leak-Proof Seal – Inverted or upright, your drink stays inside. No spills, no stress.
Removable Food-Grade Tea Strainer – Brew loose-leaf tea on the go and detach the infuser for easy cleaning.
Perfect Size – 740ml capacity (97 × 97 × 315mm) fits most car cup holders and backpack side pockets.
Available in 5 Stunning Colors – 「Làn」Aurora Limited Edition, Blush Glow, Crimson Cosmos, Rainwashed Blue, and Long Mountain Dawn.
A Philosophy in Every Sip
T-TWELVE draws inspiration from the twelve traditional Chinese time periods and the body's twelve meridians. The brand philosophy centers on the unity of heaven and humanity — using the healing power of tea and plants to nourish both body and mind. Every tumbler is a small ritual of wellness.
