Art Alternatives 6" Pro Bow Compass Set

Perfect for use by students or professionals, this set features a high-quality compass, ruling pen and extension bar. The compass features an accurate center wheel adjustment with a built-in spindle stop to prevent over-extension; a double knee-joint allows for parallel leg positioning and use with an extension beam, universal adapter or ruling pen - all of which are included. The ruling pen can also be used separately to create precise lines and drawings with ink, masking fluids or even thin paints. Packaged in a reusable plastic case, this set is easy to keep organized and transport.
