Versatile four-hole buttons provide strong, twist-resistant attachment for clothing and craft projects. The 12 mm (1/2 in) size works well on shirts, knitwear and light jackets, adding a neat, classic finish. Four sew-through points distribute stress evenly and keep stitches protected during daily use. Edges are smoothly finished to reduce snags and speed installation. The card includes 4 button(s) to outfit small projects or keep as dependable spares.
