ELAN two‑hole buttons offer a clean, low‑profile fastening for shirts, cardigans, light outerwear, bags and everyday repairs without the bulk of a shank style. This card includes 2 buttons sized 15 mm (9/16″) with a flat, sew‑through design that installs quickly and lies neatly against the fabric. Stitch by hand or machine through both holes; match the diameter to the buttonhole and tune placement, stitch length and tension so closures align consistently and wear comfortably in regular use.
