These Flight Ear Plugs are pressure equalizing ear plugs that prevent “blocked ears” and ear pain when flying, as well as subduing speaking and other noises when you want some peace and quiet. They are easy to insert and remove, and they come with a practical storage case. The Flight Ear plugs are transparent green in colour, and have a recommended life span of 150 hours of usage, if hygiene is taken care of properly. They are also made from latex-free and non-allergenic material.
