Foam Ear Plugs for ear protection in noisy environments. Reduces noise level by at least 27Db, which is a substantial reduction. Manufacturer changes from time to time so product supplied may look different to that pictured.
However we only ever supply CE Marked approved safety wear, so rest assured if you are buying these for the decibel rating or are worried about them being sub-standard, don't! We use these around our own sawmill which has noise levels of around 118Db (that's very loud by the way!)
