Introducing the first modular storage system designed for humans - humangear Stax All humangear Stax is a modular system of watertight stacking containers that click together with a simple, quick 180-degree twist for effortless organization. Each container features its own leak-tight lid, and there's a removable ClipHandle on top. Take one, take a bunch - it's your stuff, take what you want. While all humangear Stax sets can be used in infinite ways, we did design the extra-large with some special features that make it a great EatSystem - for taking your lunch to the office, going on a picnic, or just having a convenient on-the-go system for enjoying your breakfast, lunch, or dinner wherever you might be. The extra-large set comes with a set of GoBites Click utensils (fork and spoon). This set of utensils telescopes out to form comfortable utensils for everyday use but also slides down into easy-to-store utensils. This set fits in the special utility tray included in the extra-large set. This tray is also great for sauce packets, napkins, or any other small items you might need. The extra-large set also comes with the standard ClipHandle that allows for easy carrying and attaching your stacking set of containers onto the outside of a backpack or bag. We've also included two containers in this set-this way you can keep, say, your salad separate from your soup. Finally, the containers are rounded at the bases in the same shape as a GoBites spoon for easy scraping. Containers and lids are made from an FDA food-safe 5 PPContainers all click together and open/close with a simple 180-degree twistLids have silicone gaskets for superior sealingDishwasher-safeMicrowave-safe containersLids click onto container bases to help stop them getting lostCylindrical form factor slips easily into pockets, water bottle holders, etc.Easy-clean thanks to the heavily rounded container basesClipHandle securely attaches to a backpack
