Diggs’ Revol crate is designed to fit seamlessly into the home by blending in with décor. The crate is made from various plastics including polypropylene, one of the only plastics approved by the FDA for food use, along with strong and secure steel mesh wire, the company reports. The high-quality aluminum makes the crate light but still strong. The crate’s ergonomic build makes it easy to collapse with just one hand. It can be easily packed up to take on the go.
