SILLY STRING Products, based in Watertown, NY, is all about fun. We are thrilled to own and manufacture a product as iconic and a brand as playful as SILLY STRING. Since 2001, we have produced millions upon millions of cans of SILLY STRING spray streamer in our manufacturing facility in DeWitt, IA. We know that those cans, in turn, have produced a gazillion smiles and laughs from kids, families and celebrants throughout the United States and Canada. And that makes us happy! SILLY STRING Products is a division of CAR-FRESHNER Corporation, maker of the iconic LITTLE TREES automobile air fresheners.
