Extra Long length metal underwires


Premium quality metal coated with a non-stick finish These wires are 5/8” (15 mm) longer in the front only than the long wires. Use these when you need more front height. Ladies with cups over E size and will find this length more satisfactory than the Long length. The Pin-up Girls patterns in the larger cup sizes take the Extra Long Wires. You can also use Extra Long wires when making strapless bras as they come higher in the front.
