The Cose 2-in-1 Needle Threader and Seam Ripper combines a needle threader and a seam ripper in a single tool, useful for preparing the thread before sewing, undoing incorrect seams, or opening buttonholes. It's a compact accessory designed for those looking to reduce the number of loose tools in their sewing box, combining two complementary functions in one object. The seam ripper has a sharp, protected tip that cuts the thread without damaging the surrounding fabric. It's a practical accessory for both beginners and regular sewers.
