Mack’s Pillow Soft Silicone Putty Earplugs are the original moldable silicone putty earplugs, since 1962. These earplugs mold to fit virtually any ear, and stick to form a custom seal that no other earplugs can match. You can’t beat the custom fit or comfort these earplugs offer. Because they are so comfortable, they are especially ideal for sleeping, traveling, swimming, concerts or any situation that calls for extended wear time. These are the best earplugs to help prevent Surfer’s Ear and Swimmer’s Ear infections by keeping out the cold water and moisture that can lead to illness in the ear canal. They help reduce noise so that you can still enjoy a loud concert, safely, or get the sleep and rest you need. No more need to worry about losing or growing out of expensive custom molded earplugs as your ears grow and change. These inexpensive ear plugs form to fit your ears, perfectly, with each and every application.
