X-Seal & Go is a range of collapsible food containers with airtight seals. The threaded lids are simple and easy to operate, and provide peace of mind against leaks. When not in use each container collapses to a minimal height, taking up significantly less space when stored. The X-Seal & Go Large Set includes 1 size medium container and one size X-large container which nest into each other creating one compact package. X-Seal & Go containers are perfect for culinary adventures on the trail, as well as taking lunch to school or the office.
