E-A-R Classic Uncorded Earplugs - Small - Noise Protection - Foam, Polyvinyl Chloride (PVC) - Yellow - Moisture , Non-flammable, Flame , Noise Reduction - 2/Pair - 200 / Box Uncorded earplugs for smaller ears are made of nonflammable, dermatologically safe foam. PVC foam is nonirritating. Slow-recovery, low-pressure foam conforms to the shape of the ear canal for enhanced comfort and wearability. Moisture-resistance helps maintain a consistent expansion time, even in humid environments. NRR 29-decibel earplugs are 7 percent smaller than the 3M Classic earplug (and the same length) to fit comfortably in smaller ears. They are also tested to ANSI S3.19-1974.
