3M E.A.R Classic PP01002 (Pack of 250)

Classic earplugs are made from a soft energy absorbing polymer foam, which allows the user to roll the plug down for easy insertion into the ear canal and then expand slowly to form a comfortable seal against noise. Ideal for use where ever noise is a problem, either in work or leisure activities. SNR 28dB, H=30, M=24dB, L=22dB
