"Graph Gear 1000" is a mechanical pencil full of functions for drawing and painting. The weight is moderate, and the slim pen tip has a 4 mm guide pipe that makes it easy to see the line even when the ruler is applied. The grip is made of rubber to prevent hand slipping and knurled dual clip specifications. This hard rubber reduces hand fatigue. In addition, HB, H, B, and 2B can be used properly because the core hardness display window is attached. Furthermore, when you press the clip, the pen tip will be stowed, so you will not damage the pen tip in your pocket or bag.
