LEADER OF THE PACK My first reaction to the jar of Pearl Pack sachets? This packaging is so classy (especially for an odor eater) that I felt bad one of the sachets would be leaving its pretty container and spending the rest of its life in my smelly gym bag. But I got over it pretty quickly once I tossed a pack in my bag and realized a few days later that these things actually work. And just how do they work? Well, the makers won’t tell me. “It’s a family secret,” says Bob Dunklau, director of business development for Fresh Wave, the Barrington-based company that produces the packs. What we do know is that each clear mesh pack is filled with tiny plastic balls containing plant oils (a mix of pine, clove and sandalwood), and no chemicals are added. Each one is good for about 25 days, and five come in a jar. Once their odor-eating powers wane, the packs can be recycled, which means these babies are not only good for your gym bag (or car, dresser drawer, tennis shoes, etc.), they’re also ecofriendly. $16 at fresh-wave.com.
