I'm assuming ear plug but can someone elaborate on this style or what type of ear plug (water/noise) or if that is what they are or not.

Do they have a hole clear through them? If so they look like the ones that go on electronic ear plugs. The ones that shut off and cancel noise at high decibels, but electronically transmit the sound down that hole for quieter noises

Just plain earplugs. Usually attached to each other with a thin vinyl cord.

Regular washable/reusable ear plugs… I get real similar ones for my work by truck loads!

Hole in long stem and hollow but no hole on end that goes in ear.

In today’s world every fab shop has them available, maybe even required. In my day, the only thing hanging on the shop wall was a salt dispenser!

Thanks!!! I washed them well with soap and I will use them. Seem to be very good and maybe better then those soft sponge ones.
