Dont be fooled by imitations and knock-offs. Macks Pillow Soft Silicone Putty Earplugs are the original moldable silicone putty earplugs, since 1962. Macks is the #1 selling earplug brand, the #1 Doctor recommended earplug brand and the #1 brand of moldable silicone earplugs personally used by doctors in the USA. These earplugs mold to fit virtually any ear, and stick to form a custom airtight/watertight seal that no other earplugs can match. You cant 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.
