This Ear Plug is made of premium processed and lightweight PMMA synthetic material. We have decorated the front with a classic picture of a mexican skull and coated it with an epoxy resin layer partially adhering to the plexiglass (PMMA).

The rims comply around the earlobe and guarantee a perfect hold.
The Plugs are not sterilisable in an autoclave, but due to their skin friendly material they are also suitable for allergic persons.
