Ear Plug Container with rotary lid

This ear plug container is designed for a pair of custom Elacin hearing protection plugs. It consists of the core compartment and a rotary lid. The rotary lid slides around the core compartment to cover the hole for inserting the ear plugs. A notch locks the lid in the closed position. The locking mechanism makes use of the natural flexibility of the plastic. It features a ring to attach it to a key ring.
