Product Description Silverpoint is a centuries-old technique in which silver is used to draw on a specially prepared surface, leaving traces of the metal to create ones drawing. Silverpoint drawings tarnish over time creating warmer tones. Yasutomos Silverpoint Drawing Tools have a black 5 1/2 long wooden handle with an elegant bamboo shape for a comfortable grip. 99% silver points are beveled to allow for different drawing techniques and line thicknesses. Available in 1mm or 2mm widths. Tips are 9mm (3/8) long. Points can be removed by simply unscrewing them from the handles are replaced with Yasutomo silverpoint refills. While silverpoint is typically done on gesso-prepared surfaces, Yasutomo mineral paper is an excellent silverpoint substrate that requires no preparation!
