The bra underwires made of galvanized steel with a white nylon coating are ideal for repairing bras and creating your own sewn designs. They are sewn into the lower edge of the cup and provide the necessary stability for the cup to maintain its shape over time. For high wearing comfort, the ends of the underwires are rounded. The range includes bra underwires in 14 different sizes from A (75) to F (115). Since the size specifications of lingerie manufacturers often vary, the designations should only be considered as a guideline. Each retail card contains two bra underwires. They are washable up to 40 degrees.
