Using a mechanical pencil doesn't have to mean limiting yourself to plain gray lead! The Pilot Color Eno mechanical pencil is available in eight bright colors, each with matching colored lead. The leads are smudge-free and easy to erase with a regular eraser so they are perfect for drawing and sketching.
Matching refill leads can be found here. The pencil can also be used with any other 0.7 mm leads.
Each pencil comes with two pieces of colored lead.
Lead size: 0.7mm
