This 55lb tracing paper is exceptionally translucent and its smooth surface mimics the feel of vellum. Can withstand most media without warping, ripping, cracking, or wrinkling. Resistant to scraping and can handle repeated erasures without distorting. Great for calligraphy with pointed and broad-edge nibs; clear enough to see guidelines underneath without backlighting. Neutral pH allows this tracing paper to be stored without yellowing or breaking down. Also suitable for microfilming offset and letterpress, pencil, technical pens, and markers.
