Stainless steel lunch boxes have existed for decades, however they have never been fully leak proof quite simply because it is difficult to do so. This was a big (yet exciting) challenge for us as we wanted to maintain a minimal and sleek design with functional features. It took many iterations but what we have created is a carefully considered product, an engineered steel box with specifically designed radiuses on the corners for a softer ergonomic appeal. It has taken inspiration from traditional Japanese Bento Box designs with the silicone strap for added security, and the stainless steel fork makes eating on-the-go a dream.Specifications:- Stainless steel (304/18-8), including a silicone strap and a stainless steel fork.- Weight: 330g/0.73Lbs- 600 ml / 20 fl oz
