Antibacterial 316 Stainless Steel Vacuum Flask 600ml | Tea Infuser & Insulated Bottle for Hot/Cold Drinks (Black)

The entire cup is constructed of stainless steel, eliminating contact with plastic. The lid is also stainless steel: Breaking away from the traditional "plastic lid + stainless steel body" convention of insulated cups, the lid is made of stainless steel with an embedded food-grade silicone sealing ring, ensuring a leak-proof seal. 316L Antibacterial Stainless Steel: The inner liner is made of medical-grade 316L stainless steel, which is more corrosion-resistant than ordinary 304 steel and has built-in antibacterial and bacteriostatic properties, protecting the purity of every sip of water. Odorless Design: Say goodbye to the odors caused by aging plastic. The tea soup retains only the aroma of tea, without any plastic taste, and it's less likely to cause flavor transfer when brewing milkshakes or coffee. 🍵 Precision Tea Infuser, Controlled Brewing 304 Stainless Steel Filter: Equipped with a fine-mesh 304 stainless steel tea infuser, effectively separating tea leaves for a clear and bright tea soup. Tea and Water Separation Design: Place the tea leaves in the tea infuser, add water, and invert the bottle for a concentrated brew; placing it upright stops steeping, allowing you to control the tea concentration and avoid bitterness from prolonged steeping. Double-lid usage: The double-layered insulated lid can be used as an independent water cup when inverted, convenient for sharing with friends or quickly cooling hot tea. 🌡 6-Hour Hot and Cold Keeping Solution Dual Insulation Hot water remains scalding hot after 6 hours (actual temperature depends on the environment). Ice melts slowly after 6 hours, maintaining its refreshing coolness. Whether it's a hot cup of tea on a cold winter's day or an ice-cold beverage on a hot summer's day, it can handle it all. Large mouth design: The wide mouth diameter makes it easy to add ice cubes and clean the inner liner; your hand can easily reach in to wipe it clean. Portable carrying strap/anti-scalding (optional): Soft silicone carrying strap for easy carrying. 【Product Parameters】 Material Composition Inner and Outer Liners, Lid Body: 316L Stainless Steel 【Product List】 1 × All-steel insulated bottle body 1 × Stainless steel inner stopper lid 1 × 304 stainless steel precision filter 1 × Double-layered outer lid (can be used as a water bottle)
