YT-74520 Earplug Dispenser. Disposable ear plugs made of slowly expanding soft polyurethane foam. Once inserted into the ear and expanded, they are almost imperceptible. They feature one of the highest attenuation values in their class. The dispenser can be placed on a table or hung on a wall. Turning the dispenser knob dispenses the earbuds onto the user's hands.

• Ambient attenuation value: SNR 38 dB
• Number of earplugs per package: 500 pieces

Rolling the earplug in your hands, form it into a cylinder, and then insert it deeply into the ear. Hold the inserted earplug in the ear canal for about 30 seconds until it fully expands. Using your fingers or in a mirror, check that the earplug has been inserted all the way in. Only the very end of the earplug should be visible or felt.

Note:

If the dispenser mechanism over-squeezes the stopper, let it expand for about 30 seconds on its own.
