EAR PRO HEARING PROTECTION

Our EAR PRO hearing protectors are on sale at R140.00 (EX VAT) and are made to last. The silicon attachment is replaceable at a nominal cost of R15.00 (EX VAT)  a pair.   The hearing protectors should last indefinitely if they are properly cared for. Contact us for a sample. Currently the Mondi Shanduka Mill in Merebank is trialling a number of pairs.
