Unlike inexpensive stitching roulette wheels, this one is built for stability. The small diameter of the wheel and the curved shape of the shaft ensure that force is applied effectively, allowing for precise work without wasted rolling. The wheel attachment is compact, making it easy to check the stitch line. It comes with four sizes of wheels (3, 4, 5, and 6mm pitch) to match the pricking iron pitch, ensuring reliable hand-sewing. Includes 3, 4, 5, and 6mm width pitch wheels.
