These boxes are made of good quality, thick steel. The lids are also very well made and seal very well. Unlike plastic containers, it gives the satisfaction that no chemicals are leaching into the packed food . The price on overstocks was lower than at other website, so it was a no brainer to buy it from here .
This stainless sippy is excellent quality. It won't absorb odor or break if thrown like plastic. Worth paying extra and using this cup over buying multiple plastic ones that clutter the cabinets.
