Award-winning and featherweight – you just can’t beat it! Can’t you? Oh, but you can! We have completely redeveloped the classic SIGG Food Box, equipping it with some excellent new features. For example, a dishwasher-safe and microwaveable silicone insert as well as a separator made from polypropylene. And we’ve also taken another look at the already sophisticated closure system. Here’s the big box in the aluminum look. This box is made for containing solid foods, not liquids.
