Product Details

A 100% plastic-free, watertight food storage container! These containers are perfect for bringing a variety of foods on the go. They're practical, durable and lightweight for storing or transporting baked goods, lunch, stews, soups, sauces, and more. The lid has a non-removable silicone seal that has been factory-installed without adhesive and three stainless steel latches to secure the lid in place and ensure no leaks. Also fabulous for freezer storage. 

 Available in multiple sizes:​

  • 38 oz (5.75" x 3.25") - An adult-sized lunch
  • 50 oz (6.25" x 3.5") - Family leftovers or fruit salad to share

Use: The base container can heated in a toaster oven or on the stove - but be careful because it will be very hot to the touch! Please note that the lid should not be put in the oven or used on the stove. 

Care: The base container is dishwasher-safe, but the lid is not and should be handwashed in warm soapy water. Use a non-permanent marker/wax pencil to write on the container to specify contents and storage date. The marker writings wash off easily with water and friction.

Materials: high quality, food grade 18/10 stainless steel 

Made in Korea

I love these! The tight seal seems to keep food from spoiling longer, they don’t leak, and they’re lighter and less breakable than glass. I prefer these over silicone food storage because stainless never retains food smells

Good, but...

Good, but...

I have two of these. One is great, the other leaks. It took me a while to realize why, but then I noticed that the seal is twisted in the lid of the one that leaks. I can't seem to get it out to fix it, so we can only use it for drier sorts of foods. I rather doubt that it would straighten out smoothly even if I could. It would get a solid five stars if it weren't for that quality control issue.
