The professional's rotary tool for precise, clean drafting. Create accurate circles instantly without leaving an unsightly hole in your work.


Forget fiddling with screws. The iris-style mechanism allows you to adjust the drawing diameter smoothly by simply rotating the outer golden ring. It's fast, intuitive, and stays set until you move it again.

Built to last a lifetime. The outer ring is crafted from durable aluminum alloy with a matte finish for grip, while the inner aperture blades are made from corrosion-resistant stainless steel. Laser-etched scales provide quick visual reference.
| Product Type | Adjustable Rotary Circle Template |
|---|---|
| Body Material | Aluminum Alloy (Matte Gold Finish) |
| Blade Material | Stainless Steel |
| Drawing Diameter Range | 0.4 inches - 3.0 inches |

You hold the outer golden ring firmly against your paper with one hand to keep it steady. Then, place your pen or pencil tip inside the central aperture against the metal edge and trace around the circle.
It works with most standard writing and drawing instruments, including graphite pencils, technical pens, fine-point markers, and even some airbrushes, as long as the tip fits comfortably against the inner blade edge.
The numbers (1-7) on the outer ring serve as reference scales to help you quickly return to a previously used size or estimate diameters. For critical precision, we recommend checking the set diameter with a ruler before drawing.
