Helpful Tips & Care Instructions

  • 💡 Microwave Heating: Always pull up or pop open the round silicone air vent plug on the lid before microwaving. This allows hot steam to escape safely while keeping the lid snapped shut to prevent sauce splatters.
  • 🧼 Dishwasher Cleaning: Safe for top-rack dishwasher cleaning. For extended longevity, wash lids on the upper rack and avoid harsh scouring pads to preserve the smooth non-stick silicone surface.
  • 🎒 Nesting & Storage: When not in use, collapse all bowls down and nest smaller sizes into larger ones (350ml into 540ml into 800ml into 1200ml) with lids snapped on for ultimate compact storage.
  • 🍋 Deodorizing & Stain Prevention: Silicone is non-porous and naturally stain-resistant. For intense sauces (like curry or marinara), soaking briefly in warm water with a slice of lemon or baking soda keeps your container fresh as new.

Bought the 4-piece nesting set for camping and road trips, and they are phenomenal. The silicone is thick, sturdy, and doesn't bend or collapse accidentally when filled with hot chili or soup. The 4 side snap buckles lock with a reassuring click, and they survived multiple trips in our cooler without a single drop leaking. Cleans up easily on the top rack of the dishwasher. Easily one of the best kitchen storage purchases I've made this year!

This collapsible lunch box has completely upgraded my office meal prep routine! It holds a full lunch portion (I got the 800ml size), and once I finish eating, I just pop it down flat and slip it into my work tote. The steam vent on the lid is ingenious—you can microwave your food with the lid on and never have to clean food splatters inside the office microwave. 100% leak-proof even with dressed salads and pasta sauce. Shipped fast and beautifully packaged!

Yes, absolutely! The container is made from premium high-grade platinum silicone that withstands extreme temperatures from -40°F up to 446°F (-40°C to 230°C). It can go directly from the freezer to the microwave and is 100% safe for top-rack dishwasher cleaning.

Before placing the container into the microwave, simply pull up or open the small circular silicone vent plug located on top of the lid. This allows excess steam to vent safely while keeping the 4-snap lid locked, preventing messy sauce splatters.

Yes! The lid features an airtight food-grade silicone sealing gasket and 4 reinforced snap-lock buckles on each side. When all four buckles are clicked shut, it creates a 100% airtight and leak-proof seal that prevents spills in your bag.

Each container collapses down to approximately 1/3 of its expanded height (around 1.2 inches thick), freeing up over 60% of storage space. When empty, multiple sizes can nest inside one another for ultra-compact cabinet or pantry storage.
