Premium quality metal coated with a non-stick finish. These wires are best suited to bras with slightly lowered centre fronts or ones where a long wire is slightly too long for the casing. The front arms are shorter by 10 mm (3/8") than the long wires.
Bra-Makers Supply have published a great document of Must-Know Information for underwires to help you calculate the correct wire size. Click here to open the pdf in a new page.
If you have a wire from an old bra that fits you well, there is also a chart that you can print off at 100% to check the equvalent wire size. Click here to open the pdf in a new page.
