Dual-Function Design: Use with tracing paper to transfer colored lines or alone to create perforated cutting lines on fabric, paper, or leather. Industrial-Grade Construction: Hardened steel needles are individually stamped and locked into the wheel, lasting 3x longer than standard tracing wheels. Precision Perforations: Engineered needles create evenly spaced stitching holes, perfect for marking sewing lines, leather goods, and hand-stitching projects. Comfortable Ergonomic Handle: Solid wooden handle provides a firm, comfortable grip, reducing hand fatigue during extended crafting sessions. Versatile Use: Ideal for leatherworkers, fashion designers, quilters, and cosplay creators. Works flawlessly on leather, vinyl, felt, and all types of fabrics.
