Koala Tools Wide-Angle Isometric Grid 3D Sketchbook

Isometric grid is "stretched" horizontally to create a lower vantage point, which produces a more realistic, CAD-like 3D effect. Thin, light teal lines can be lightened and erased easily with photo editing software after scanning. Terrific for architecture, furniture and product concept sketches. Paperback, measures 7-1/2 x 9-3/4". 60 pages.
