Clearprint 1000H and HP Design vellum drawing paper pads. 16# and 24# medium to heavy weights, acid-free drafting vellum paper. Available plain and unprinted, or printed with a non-reproducible blue grid on one side (Fade-Out). 100% new cotton fiber vellum paper is excellent product for manual drafting. Transparentized without solvents to produce the proper translucency, as well as the legendary Clearprint archival quality, strength, eraseability, no ghosting, and redraw characteristics. Fade-Out blue grid lines are accurate and exceptionally clear, sharp, and visible, but will not reproduce on blueprints. All grids are printed on the underside of the paper to prevent removal during erasures. Pre-printed grids provide exact reference points for detailed drawings. High tensile strength helps prevent tears. Smooth transparent surface suitable for pencil or ink. Quality-made in the USA.
