Good size, lightweight

Good size, much lighter weight than the glass containers I had been using and with a better seal against spilling. I enjoy the patterns on the tops of the lids

I absolutely love it!

I’ve been using a different-shaped lunch box from this brand for about five years, and it’s still going strong. I decided to add this round one because I thought the shape would be convenient for certain types of food. It’s incredibly durable, feels very well made, and I love that the stainless steel makes it hygienic and easy to keep clean.
