Meteors PlugStation allows the earplugs to drop right into your hand so they dont fall on the floor, or trays collecting dust and contaminants. Each PVC-Free dispenser is sealed and disposable plus completely recyclable. Meteors foam earplugs have a unique curved design that provides exceptional comfort and are PVC-Free. The contours follow the shape of the ear canal which means less pressure at the smallest diameter of the earplug. They have the highest independently tested NRR 33dB and have a bright green color for easy compliance checks.
