Aqua Pencil Kit
Comes with an Aqua Pencil, Tether, and an Aqua Pencil Lead Pack sleeve of spare leads.
This very cool, and very functional - pencil stays put, never needs sharpening, and clips handily to the side of your slate. The tether allows you to attach it to your slate so it is always there when you need it.
The Aqua Pencil is a simple mechanism that allows you to feed graphite as you need it by twisting the end. The graphite is 2 mm in diameter. It resists breaking and is 3.5" long for plenty of supply. The graphite is easily replaced when it gets low. The ergonomic shape fits comfortably in your hand with or without a glove.
