Embassy shank buttons feature a built‑in loop on the back to create space between button and fabric. This 3‑pack measures 15 mm (5/8 in) in diameter and helps layered or bulky fabrics drape cleanly without puckering. The smooth face presents a tidy, elevated look and is comfortable to grasp. Sew onto coats, cardigans, knitwear, bags and costume pieces for durable closures that won’t compress thick layers.
