ELAN 2-hole sew-through buttons are a neat, low-profile option for apparel repairs, mending, and new makes that need a traditional closure. You’ll receive 4 button(s) at 11 mm (3/8 in) diameter, sized for plackets, cuffs, childrenswear, knitwear, and small accessories. Measure existing buttonholes before stitching, and use even tension and matching thread so the buttons close cleanly and wear comfortably.
