Once again I wore out one of the cheap ($2.00) mechanical pencils I normally buy. So this time I decided to "upgrade" to a better one. On Amazon, I found a set of three Rotring pencils in three different sizes of lead. And they are so comfortable to write with!
Ideally, I want to use an HB lead in the 0.35 size, a B2 in the 0.5, and a B4 in the 0.7. A good range to draw with!
