Shank‑back sewing button sized 23mm (7/8"), packaged 2 per card. The raised shank keeps stitches hidden and leaves clearance for thicker fabrics so closures fasten smoothly without puckering. Well suited to coats, jackets and knitwear, it provides a tidy, low‑profile finish that helps heavier garments drape cleanly. Use as a replacement or for new makes when you want a polished closure on outerwear, accessories and costume work.
