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.
