Rite in the Rain All-Weather Mechanical Clicker Pencil w/ 1.3mm Black Lead

The knurled-metal grip and one-hand click lead advancement offer glove-friendly handling. The 1.3mm lead won’t snap at the tip or break in the shaft, so you can write in a notebook just as easily as it can mark lumber. Simply drop a single lead into the shaft under the eraser cap. Refills for the thick leads and clean erasers are available.
