12-Pair Heavy-Duty Carbon Steel Bra Underwires – Replacement Support for D & E Cups

Restore the structure and support of your favorite intimate apparel with this bulk set of 12 pairs of premium carbon steel underwires. Specifically engineered for larger cup sizes (D and E), these heavy-gauge metal supporters provide the necessary rigidity to maintain bra shape, prevent sagging, and offer long-lasting comfort.

Key Features:

• Industrial-Grade Carbon Steel: Crafted from 100% high-quality carbon steel, these underwires offer superior strength compared to standard alloy wires. They are designed to withstand daily wear and frequent movement without snapping or losing their "U" shape.

• Specialized Support for Larger Cups: These heavy-gauge wires are precision-formed to provide the structural lift required for D and E cup sizes. The sturdy metal core ensures balanced weight distribution for a more comfortable fit.

• Bulk 12-Pair Value Pack: This set includes 12 matching pairs (24 pieces total), providing an affordable solution for multiple repairs or for custom lingerie designers and seamstresses.

• Durable White Protective Coating: Each wire is finished with a smooth, white protective tips/coating to prevent the metal from poking through the casing and to resist corrosion from moisture or skin oils.

• Sustainable DIY Repair Solution: Don't discard an expensive bra just because of a snapped wire. These replacement parts allow you to extend the life of your wardrobe, saving money and reducing waste through simple home sewing repairs.

Sewing & Repair Tip:

To replace a broken wire, carefully make a small incision at the end of the underwire casing (the "channel"). Slide out the old wire and insert the new carbon steel replacement. For the best results and to prevent the new wire from poking through, reinforce the end of the channel with a tight "zigzag" or satin stitch (bartack) using heavy-duty thread.
