Specifications

The laminated structure of WorkSafe protectors is produced from a unique, durable soft flexible plastic. The earplug easily fits into the shape of the hearing canal within a few minutes, due to the body heat and thus is very comfortable to wear.

Cleaning

The protectors are to be cleaned easily using lukewarm water and little soap. The lifetime depends on the maintenance and the using frequency.
