Better than wax! From strengthening your thread and preventing tangles to reducing hand fatigue, this is a sewing kit must-have. Thread Magic was designed to condition thread and make it more manageable. It reduces thread friction and drag by 400% more than wax-treated thread, and 700% more than untreated thread. This means less hand and wrist fatigue plus less wear on fabric. It creates an invisible and virtually impenetrable coating on your thread to protect it from colour-damaging UV rays, mold and mildew.
