Retro Precision Dotting Pen Set Mechanical Gear Driven Fine Point Kit Roller Wheel Drawing Scriber Dashed Lines

Material: Metal Size: 8cm*6cm/3.14in*2.36in 1. Pure mechanical gear transmission structure, no battery required, high-precision and uniform line and dot drawing: The all-metal mechanical linkage gear design does not rely on batteries or ink consumables. Relying on stable gear transmission, it can draw uniformly spaced dashed lines, dotted lines, and dotted-dash lines with consistent speed. Compared to ordinary ruler hand-drawing, the lines are neat and without distortion, and the dots are of uniform size, significantly improving the accuracy of drafting and leather pattern making. The retro metal body combines texture and durability. 2. Four replaceable gear wheels, switching between four professional line types in one second: Equipped with four functional dot-marking wheels, it can respectively achieve solid dots, short dashed lines, dotted-dash lines, and special interval lines. Gear changes can be completed in seconds; meeting various line needs for blueprint engineering drafting, leather cutting marking, DIY pattern drawing, and retro hand-painted decoration. One tool replaces multiple marking rulers, reducing desktop clutter. 3. Adjustable nib height design, adaptable to various material thicknesses: The side knob allows for free adjustment of the metal nib, adjusting the depth of the stroke accor-ding to the thickness of paper, leather, and cardstock. It glides smoothly along the edge of a ruler without deviation, and the metal tip provides stable ink fl-ow without skipping or smudging. It leaves clear and even lines on both soft and hard paper, vegetable-tanned leather, and thick cardstock. 4. Thickened stainless steel unibody design, wear-resistant, corrosion-resistant, and dur-able: The entire device is made of thickened stainless steel through stamping, with a non-slip texture, rust-proof, and scratch-resistant. The gears mesh tightly without loosening, preventing slippage or widening gaps even after repeated use. The metal edges are rounded and burr-free. The compact body makes it easy to store and carry in craft studios, drafting desks, and leather workshops. 5. A versatile professional hand tool suitable for various scenarios. Whether for architectural blueprints, mechanical drafting, marking stitching points on leather goods, or creating vintage-style hand-drawn journals, this tool is highly efficient. Compact, portable, and solidly crafted, it's an essential high-precision auxiliary tool for craftspeople, drafting designers, and hand-drawing enthusiasts. Package includes: 1 set
