Low-profile shank buttons sized for knitwear, bags and tailored pieces. The 21 mm (7/8") diameter sits slightly above the fabric to ease buttoning and reduce abrasion. Card of 2 supports multi-button closures or keeps spares handy. The closed shank guides thread neatly and protects it from wear. Ideal for coats, cardigans, accessories and costume work. Match button size to loops or buttonholes and add a thread shank when sewing through thick layers.
