3M 391-1004 E-A-Rsoft™ Yellow Neons™ One Touch™ Foam Earplug Refill

Foam Earplug Refill 3M 391-1004 E-A-Rsoft™ Yellow Neons™ One Touch™
A high-performance hearing protection product from 3M, ideal for use in areas with hazardous noise levels. These earplugs are made from Polyurethane Foam, featuring soft foam and slow-recovery foam characteristics that allow users enough time to roll the earplugs into a small cylinder and easily insert them into the ear canal before the foam slowly expands to fully seal the ear canal for a snug and comfortable acoustic seal. The tapered shape and smooth, soft texture provide a proper fit for most ear canals and reduce pressure inside the ear, allowing for longer, more comfortable wear. Another key feature is the brightly-coloured, neon-yellow design that offers high visibility, making it exceptionally easy for safety supervisors to verify proper hearing protection compliance in the workplace. The 391-1004 model is specially designed as a refill bottle for use with the tabletop or wall-mounted 3M™ One Touch™ Earplug Dispenser (model 391-1000), facilitating hygienic dispensing: just a simple turn dispenses 1 pair of earplugs without individual plastic packaging waste, reducing litter and offering convenience in industrial environments.
