Not only does the Mitsubishi uni mechanical pencil come in every size you need, but it also has a ring on it that assists you in keeping track of the density of lead loaded in the pencil as well as the lead size. The color of the ring on the barrel indicates the size and you turn the ring in order to select the lead density.
Note: do not load more than two leads into this pencil at one time to avoid jamming.
Available in .3 (yellow), .4 (orange), .5 (red), .7 (blue), and .9 (green)
