KLASSÉ dressmaker pins are straight pins for general sewing, pattern layout, and construction when you need pieces held in place before stitching. The box contains 500 pins at 30 mm (1 1/8"), providing plenty for long seams, cutting layouts, fittings, and frequent pinning sessions. Pin along the seam line, remove as you sew, and keep the box closed between uses to reduce spills and protect points.
