This is the same type of cord used by paratroopers during World War II. The 16 ft. cord is 4mm in diameter, quick drying, fusible, resistant to mildew and extremely durable. Crafters can use it to create survival bracelets, key chains, monkey fists and more. Combine colors to make projects for school, sports team paraphernalia or to create survival tools.
