There are a total of 10 clips, 5 pink and 5 red. Clip size: Approximately 10 x 27 x 15mm Material: Polycarbonate, stainless steel These clips are useful in various situations, such as temporarily holding thick fabrics, zippers, bias tape, areas where fabric overlaps and becomes thick, and for use with a serger. The large opening width (maximum approximately 10mm) makes it easy to grip thick sections. The flat base prevents fabric from lifting and allows for easy fabric feeding. Seam allowance guides for 5mm, 7mm, and 10mm widths are provided.
