Hook Free Wire Loop The wire loop is slim and smooth to prevent snagging of fabric or buttonhole threads. The steel wire loop narrows at the tip to lock each button in place, making it easier to pull through the buttonhole. Benefits: reduces snagging, ensures secure placement, and improves threading reliability on standard buttonholes. Smooth Zipper Hook A rounded steel zipper on the button closure enables easy operation on zipper, pants, shorts, jackets, and other garments. The zipper hook is narrow with rounded edges to slide into most zipper pullers. Benefits: smooth, reliable threading of zippers across common garment types. 24-Hour Online Service 24-hour online support service. If you have any questions, please contact us.
