Mack's Earplugs

In 1962, an up-and-coming symphony orchestra musician crossed paths with an elderly pharmacist who wanted to sell his earplug business, and a deal was struck to purchase the company.  The only product, Mack's Earplugs (named after the previous owner) was made of a moldable clay mixture. Being the avid swimmer he was, he thought a stickier, more malleable substance would better seal out water, thus preventing the annoyance of water-clogged ears. Through much trial and error, as well as different production techniques, he discovered a very unique substance that became the world's first moldable silicone earplugs.
