This plastic whale bone with 8 mm width and 1,2 mm thick can be used as boning in a corset, a bodices, in underwear like the sides in a bra or a longline bra and in swimwear etc.
Easy to work and waterproof.
Cut it to desired length with a pair of pliers or scissors, and then round off the ends with foot- or nail file or sandpaper.
This boning can be moulded using a hot iron, remember though to have a piece of fabric between the iron and the boning.
