The design of E.A.R Push-Ins Earplugs eliminates the need to roll down the earplugs for fit prior to inserting in the ear, which helps prevent hand-to-ear contamination that can occur with roll-down earplugs. Each Push-Ins earplug has an EARform soft foam tip for exceptional comfort and performance, and a handle that makes insertion and removal easy. NRR 28dB. Tested to ANSI S3.19-1974 standard. 100 pair per box. Sold by the Box.
