Rustproof Vacuum Insulated Coffee Flask

Size: 7.5 cm × 16 cm. Weight: light and balanced for daily carry. Capacity: 450 ml. Material: High-grade stainless steel — inherently rustproof, non-reactive, and dishwasher-safe (top rack recommended). Vacuum insulation delivers measurable thermal performance: hot drinks remain noticeably warm after 4–6 hours; cold drinks stay refreshingly cool for 6–8 hours under typical UK ambient conditions. Airtight lid prevents evaporation, oxidation, and ingress of dust or moisture. Suits diverse routines: equally functional for early shifts at the hospital or school, remote work sessions, train journeys, gym visits, or garden gatherings — its neutral form factor blends into professional and casual environments alike.
