Durable 4-hole sew-through button provides a very secure attachment and a neat, flat profile that sits comfortably against fabric. At 12 mm (1/2"), it suits shirts, knitwear, childrenswear, bags and home-sewing projects, and it also works well for craft décor and card-making. Edges are smooth to help prevent snags, and the compact card is convenient for repairs or coordinating accents across multiple items.
