  • Built-in Tea Infuser & Leakproof Security The integrated tea infuser compartment allows steeping loose leaves directly in the flask, while the silicone-sealed lid and copper-coated inner layer ensure 360 leakproof performance doubling as a drinking cup and isolating external temperatures for spill-free portability in bags or cup holders.
  • Ergonomic Handle & Anti-Slip Base Featuring a soft-grip retractable handle for comfortable carrying during travel and a weighted silicone base that stabilizes the flask on uneven surfaces (e.g., car consoles or picnic tables), this design prioritizes safety and convenience for active lifestyles.
  • Easy-Clean Design & Durable Portability The wide mouth (compatible with ice cubes) and smooth 316 steel interior resist flavor retention, enabling quick handwashing; its compact profile (33 10 9.5cm) and lightweight build (776g) make it a space-saving essential for backpacks, gym bags, or drawers.
