Earplugs are easily lost and difficult to store. But Warren, Mich.-based Mack’s Earplugs, the No. 1 doctor-recommended earplug brand in the United States, has solved this storage dilemma by creating Wallet Earplugs. The product comes in a convenient fold-up package that fits unobtrusively in a wallet or purse. To use them, consumers just take them out of the package, roll them up, and place them in their ears. The product is ideal for air travel, concerts, construction workers or gun enthusiasts. A box of four pairs of earplugs retails for a suggested $3.99. To find our more, visit www.macksearplugs.com.
