316L Insulated Bottle - Medical-Grade Steel & Tea Filter

PREMIUM 316L MEDICAL-GRADE STEEL: Unlike standard bottles, this interior is crafted from upgraded 316L stainless steel. It offers superior resistance to corrosion, oxidation, and residue, ensuring your water, tea, or coffee stays pure with no metallic taste.

EXCEPTIONAL TEMPERATURE RETENTION: Engineered for performance. Tested with 95°C water at room temperature (20°C), this flask maintains heat effectively: ≥86°C after 4h, ≥72°C after 6h, and ≥58°C after 12h. Perfect for keeping drinks hot all day or icy cold in summer.

INTEGRATED TEA FILTER & POLISHED LINER: Includes a dedicated 316L stainless steel tea filter for a debris-free brewing experience. The inner wall features a finely polished, non-porous finish that resists bacterial growth and makes cleaning effortless.

SILENT NON-SLIP SILICONE BASE: Designed with modern professionals in mind. The bottom is equipped with a soft silicone pad that prevents slipping and eliminates the loud "clanking" noise when placing the bottle on desks or meeting tables.

ELEGANT MATTE FINISH & ERGONOMICS: Features a stylish matte exterior paint that provides a comfortable grip and resists fingerprints. The polished rounded rim ensures a smooth, safe drinking experience for your lips.
