Good Measure
O'lipfa 5inx24in Lip Edge Ruler
$ 19.50
The lip edge works like T-square. Openings at intersecting inch grids for accurate cutting. The numbers run in both directions at each end for both left- and right-handed cutting. Note: It does not have an accurate 90 degree measurement and should not be used as such. The Omnigrid Omni-Edge rulers are 100% accurate.
