No clicking, no twisting, no sharpening! The Ticonderoga Sensematic is the world's only auto-feed mechanical pencil. Simply touch the pencil to paper and the Sensematic "senses" how much lead you need, advancing just the right amount as you write. You'll never again have to stop writing or drawing in order to sharpen your pencil.

The Ticonderoga Sensematic includes an extra eraser and three additional leads. The refillable 0.7 mm, #2 pencil leads ensure that you'll never need another writing tool.
