Clover says:"Our Black Gold Hand Sewing Needles are the finest and most exquisite needles ever. The needle is 30% less friction-resistant than conventional hand-sewing needles. The needle is polished along the axis and coated with ultra-thin black plating for anti-rust resistance. Experience astonishing smoothness with each use. These needles are durable, superior and so smooth, wherever and whatever the application may be."
They are available in size 9, size 10, size 12 and a mixed size pack of 9,10 and 12.
