Moldex Pura-Fit Earplugs To Go 50 pairs contains user instructions in a resealable box. This pack of ear plugs are well suited for workers who change workplaces often and want to take along more than just one pair of plugs in their car or toolbox but don’t want to carry a whole box. Pura-Fit ear plugs are tapered so they are easier to insert in any size ear canal. And they are longer too, so they are easier to grasp. The special foam is formulated for softness and comfort, and the outer surface is smooth, so it doesn’t irritate the ear canal.
