This is a nice quality lunch bag. It looks to fit most of my medium-sized Tupperware, but my larger ones don't fit. I've found myself taking less to work and adding in a lot small snacks that make up my lunch. At first I found this bothersom, but now I'm grateful for the variety. The two straps make it easy to carry on my arm, the longer strap makes it easy on my shoulder. Overall I love using it and it does the job!
