3M Aearo E-A-R Classic Soft Uncorded Ear plugs Thermal (200 Pairs)

These cylindrical uncorded earplugs are made of patented new foam; have a smaller cell structure; feel smoother than other foam; and, react to the wearer's body temperature. These thermal-reactive plugs start out firm enough to make roll-down and insertion easy. As the foam warms to the wearer's body temperature, it becomes softer and shapes to the individual's ear canal. This "shaping" allows the plugs to form an excellent seal against noise (NPR 31 dB). With time the foam continues to soften for added comfort.

200 Pairs per box.
