A premium-quality UK-made underwire casing manufactured using patented Fortitude technology, offering an exceptional combination of softness, strength, and durability.

This tubular channel tape is ideal for enclosing underwires in bras, but is equally useful for lightweight corsetry, costume making, and boning applications. The casing measures 15mm wide when laid flat, with the internal channel typically accommodating steel or plastic bones up to approximately 10mm wide, depending on stitching allowance and application.

Despite its soft handle and comfortable feel against the skin, this casing is extremely strong and designed to withstand the stresses of regular wear and laundering.

Available in White or Ivory.
