YATO Disposable Earplugs 38 dB 250 pairs

Disposable earplugs, made of slow-expanding soft polyurethane foam. After being placed in the ear and expanding, they are almost unnoticeable to wear.
The earplugs belong to the products with the highest attenuation value in their class.
The dispenser can be placed on a table or hung on a wall. By turning the knob, earplugs are dispensed directly into the user's hand.

Usage:
Roll the earplug between your palms into a cylinder and insert it deep into the ear. Hold the end of the inserted earplug in the ear canal for about 30 seconds until it fully expands. Check with your fingers or in a mirror that the earplug is inserted all the way into the ear — only a small end should be visible or felt.

Note:
If the dispenser mechanism compresses the earplug too much, let it expand on its own for about 30 seconds before use.
