A neat shank button measuring 12 mm (1/2 in) that adds depth and a polished look. The built-in shank lifts the button off the fabric so layers move freely and the stitching is protected from abrasion. Ideal for blazers, coats and cardigans or where thicker fabrics need a little stand-off. Suitable for hand or machine sewing with strong thread. Perfect for replacements, tailoring and costume work. Each card includes 4 button(s).
