My husband takes a few slices of bacon to work as part of his breakfast. He used to heat them in plastic storage containers and the bacon grease would melt the plastic! Toxic mess! I purchased two of these little Pyrex containers and they are perfect. Low profile so they fit in a small cooler. No melting in the microwave. Thick and solid so no worries about breaking. Plus, they were sold as singles instead of in sets of varying sized containers.
