Honeywell 1013046 Howard Leight LS400 Max Refill (Pack of 200 pairs)

POLYURETHANE FOAM: Soft foam delivers superior long-wearing comfort and solid performance. SMOOTH, SOIL-RESISTANT SKIN: Prevents dirt or other substances from accumulating on skin or entering ear canal. BELL-SHAPED DESIGN: Delivers maximum in-ear comfort without backing out of the ear canal, easier to insert. STORAGE INFORMATION: All earplugs should be stored before and between usages in a way that protects them from dirt, grease, and other contaminants. CARE INSTRUCTIONS: Disposable earplugs are made of either TPE (Thermoplastic elastomers) or polyurethane foam. Washing and cleaning of disposable earplugs are not recommended. These plugs must be disposed of and replaced after each wearing. Excessive moisture reduces the attenuation and slows down the foam recovery which may lead to improper fit.
