Classic shank buttons sized 18 mm for coats, knitwear and structured bag straps. The raised shank keeps fabric from bunching and helps heavier layers drape cleanly. Pack includes 2 piece(s), ideal for replacements, repairs and embellishing new projects. Easy to hand‑sew and durable for repeated wear. Great for school uniforms, outerwear, totes and costume work. Suitable for hand or machine sewing with standard thread.
