Master Series Office Stainless Steel Vacuum Flask

This Master Series thermos cup features a 316L stainless steel interior, which is more corrosion-resistant and has better acid and alkali resistance compared to regular stainless steel. It is ideal for holding various beverages such as tea, coffee, and juice. The body is made from 304 stainless steel, and the overall structure is a double-layer vacuum design, which blocks heat conduction and convection to provide long-lasting insulation, keeping hot drinks warm and cold drinks cool.

The filter is made of 316L stainless steel and silicone rubber, allowing you to switch between different tea brewing methods and effectively separate tea leaves from the liquid. The lid is composed of 316L stainless steel, zinc alloy, aluminum alloy, and PP, combining elegance with durability. The cup mouth is thickened and rounded for a comfortable touch and easy cleaning. The body features a simple, solid color design that resists paint chipping with extended use.

The product is available in two sizes, 420ml and 500ml, weighing 0.28kg and 0.36kg respectively, making it lightweight and portable. The overall craftsmanship is meticulous, and it comes with custom packaging from the Master Series, making it suitable for business use, home tea-drinking, or as a premium gift.
