Our new patented sew through flex stay is our latest improvement to this very popular product. The patented sew through technology saves time in the sewing over traditional spiral metal boning. Flex stays also give you a 66% weight reduction over traditional spiral boning which is a huge plus with the sleeker lightweight products being designed today. We currently manufacture seventeen different lengths from three to eleven inches. We are also adding different lengths if volume warrants. Please call or e-mail to request a flex stay sample package today!
