“Onyx Containers was launched by new parents who couldn’t find something on the market and filled the gap with their own innovation. Before Onyx, your only alternative to plastic food storage was glass (usually with a plastic lid!). Onyx is made of food grade stainless steel; A material that is light, durable, safe at a range of temperatures, easy to clean, functional, attractive, and affordable. Their extensive line covers everything from divided containers perfect for school lunches to popsicle molds and every shape and size container in-between .”
