Cut out perfect circles from 1" - 5 1/2" diameter with this handy circle cutter. Guide marks printed on the transparent disc let you easily plot different size circles in 1/16" increments. The double-sided blade allows cutting in both clockwise and counterclockwise directions. Three blades are included. The blade attachment tool and refill blades store neatly inside the ergonomic, soft-grip handle. Use with a self-healing mat, not included.
