Sew-on hooks and eyes provide a discreet, secure closure for waistbands, plackets and necklines on skirts, pants, dresses, costumes and lingerie. The 9 mm (3/8") size is ideal for light to medium-weight fabrics and invisible fixes. Each paired hook and eye has a rust-resistant finish for durability. Use them at stress points to keep zippers closed, reinforce snaps or create adjustable overlap closures. Hand-sew through the side loops and align edges neatly for a clean, professional result.
