Blackwing's first square pencil, a tribute to the art of woodworking.
Each pencil is made from special slats with serrated joints, created by combining two short slats. This creates its square body with an extra-wide face so that the serrated joints are visible on each pencil.
The number 21 represents the wisdom of "measure twice, cut once." The pencil's firm (2B) graphite is perfect for measuring and marking cutting lines, and then measuring them again.
Compatible with all Blackwing pencil sharpeners.
