400ml Premium Stainless Steel Vacuum Flask

Compact Hydration
Size matters. The 400ml design strikes the perfect balance between capacity and portability. It is small enough to fit in standard car cup holders, children’s lunch boxes, and slim briefcases, yet holds enough liquid to keep you hydrated or caffeinated for hours.

Advanced Thermal Performance
Using industry-leading double-wall vacuum insulation, this flask creates a thermal barrier that blocks heat transfer. Whether it’s a hot tea on a winter morning or chilled juice on a summer hike, the internal temperature remains stable while the exterior stays cool to the touch.

Built to Last
Stop replacing cheap plastic bottles. This flask is constructed from robust 304 (18/8) stainless steel, known for its resistance to oxidation and corrosion. It withstands drops, bumps, and daily wear and tear. The interior is non-porous and safe, ensuring no metallic aftertaste.

100% Leak-Proof Reliability
Travel with confidence. The screw-on lid locks tight with a high-quality silicone ring. You can store it sideways in your bag next to your laptop or clothes without worrying about drips or leaks.
