Need to expand your patio storage, but have limited space available? Store your things outside in a Lifetime Storage Box. The rigid, double-wall, high-density polyethylene (HDPE) construction makes the box strong and durable, sturdy enough to be used as a patio bench. It's UV-protected construction, and the weather and water resistant seal helps keeps the interior dry. The spring-hinge lid opens greater than 90, won't slam shut, and is lockable.
