Porcelynne Spring Steel White Corset Boning Stays - 1/2" Width - 11" Length (10 Pieces) Stays are great to use for costumes, evening or bridal wear. There are times when a few bones in a daywear garment are indispensable, for example, for helping a seam, skirt yoke, oversized waistband, square neckline, or decorative fold stay put. Boning is tipped with several layers of a thick, white, water based lacquer to prevent fabric wear.
