With a 1000ml capacity, the Boss Vacuum Flask KE-1000 holds liquid at temperature via double-wall vacuum insulation. Under the food-grade exterior, a glass inner coating prevents chemical leaching or metallic taste. This 1-liter thermal flask maintains heat during typical Bangladesh load shedding when electric kettles won't run.
Key Features
- Glass Inner Coating: Internal glass lining provides thermal retention for 12 hours. Prevents flavor transfer between different drinks.
- Double-wall Insulation: Vacuum-sealed construction minimizes heat transfer through the flask walls. Keeps tea hot or water cold.
- Integrated Drinking Cup: Threaded lid doubles as a 150ml serving vessel. Eliminates the need for external glassware.
- Easy-Pour Spout: Mechanical spout controls liquid flow with a single press. Stops spills during roadside travel.
- Food-Grade Material: External housing consists of BPA-free, non-toxic polymer components. Resists degradation from daily handling.
