Thanks to the built-in ratchet mechanism on the handle, you can easily cut perfect circles ranging from 1.6 cm to 22 cm in diameter without straining your wrist. Ideal for use on paper, vinyl, film, cardboard, thin leather and similar materials.
 
The included protective rubber pad protects your projects from unsightly spike holes, ensuring a professional finish. When using the pad, circles from 4 cm to 22 cm in diameter can be cut.
Caution: Applying too much force may cause the pin to pierce through the material.
