Product Description
This Ring Ruler is the first size-adjustable, circular ruler.It has been designed to make the drawing and measuring of circles and arcs amuch simpler, more efficient experience by eliminating the cumbersomepivot-point system. Not only is the natural feel of expanding and contracting acircular ruler more ergonomic than using a needle compass, it is also quicker,safer and provides the more useful circular metrics of diameter andcircumference (arc length). Rule is 19" long; maximum diameter is 6".One of the best features of the Ring Ruler is its simplicity. This makes it agreat learning tool for children - especially ones too young to handle a circlecompass.
