Elevate your daily hydration with the OTE Jumbo Insulated Tumbler, a high-capacity "portable reservoir" designed for the modern, on-the-go lifestyle. Blending chic aesthetics with heavy-duty performance, this tumbler is the perfect companion for long commutes, office hours, or weekend adventures. Its oversized design ensures you stay hydrated longer without the need for constant refills, while the premium medical-grade materials guarantee that every sip remains fresh, pure, and at the perfect temperature.

Key Benefits

Medical-Grade Construction:** Built with premium SUS316 medical-grade stainless steel, this tumbler is exceptionally resistant to corrosion and oxidation. It is designed to handle everything from hot coffee to acidic juices without lingering odors or metallic tastes.

Advanced 8-Layer Insulation:** Featuring a sophisticated 8-layer temperature-locking structure, the vacuum-insulated walls provide superior thermal retention. It keeps your beverages ice-cold or piping hot for extended periods, regardless of the external environment.

Innovative Dual-Drinking Lid:** This versatile lid offers two distinct ways to hydrate. Use the integrated straw mode for spill-resistant, small-gulp sipping that prevents choking, or switch to the direct-drink mode for a smooth, high-flow hydration experience.

Ergonomic Silicone Handle:** The integrated "Linging" handle is crafted from soft, food-grade silicone. It is specifically designed to be gentle on your hands and fingers, making it easy to carry your heavy-duty tumbler wherever life takes you.

3. **Drinking Modes:** Simply toggle between the straw port for casual sipping and the wide-mouth opening for rapid drinking.

4. **Secure Seal:** Ensure the lid is tightened properly and the silicone seals are aligned to maintain the vacuum and prevent leaks during transit.
