With its minimalist and functional design, the Vacuum Lunch Box has a simple yet elegant style. The air pressure cover can be removed with one push, and the ergonomic design of the long, wide handle makes it comfortable to use. The stacked boxes inside also feature a small handle that makes it very easy to take them out. The exterior is made of 316 marine-grade stainless steel, which is strong, environmentally friendly, and ensures a long service life.
