Mono pencils are made with superior, extra-refined high-density graphite. These long lasting pencils feature strong points making them extremely break resistant. They also wear slowly, all the while producing smooth, dense lines when writing or drawing. The smear-proof lines give drawings a crisp, clean appearance. This six-piece carded drawing set comes with one pencil each of 2H, HB, B, 2B, 4B, 6B and a round Mono Zero Eraser.
