Frequently Asked Questions
How do I draw with it if there's no center needle?
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.
What kind of pens can I use?
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.
Are the numbers on the ring precise measurements?
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.
