These ingenious airtight stainless steel containers are the answer to so many various prayers. Storage mavens, leftover lovers, packed-lunch aficionados, zero-waste supporters, and detesters of tupperware drawer mayhem REJOICE! These sleek leak-proof friends can be packed, stacked, stashed, and stowed in a purse or picnic with no worry of spillage-three tiffin-style steel clasps keep the lid on tight. Plastic-free stainless steel construction looks slick AND can be used in the freezer, reheated directly in the oven, or washed in the dishwasher (just remove the silicone-gasket-lined lid first!). We love to write the contents on the outside with one of our trusty wax pencils. Graduated sizes nest. ~3" / 8cm diameter / .6 cups / 140 ml.
