Zebra Drafix Technical Pencils work perfectly for sketching or precise technical drawings as an ideal tool for both students and professionals.
Click-cap slides off to access the eraser underneath. Eraser tip also pulls off for easy loading of refill lead into the pen barrel.
Pencils come pre-filled with 2 sticks of HB lead. If you choose to refill with another degree of hardness, the colored dial in the middle rotates to display either HB, F, H, 2H, 3H, 4H, 2B, or B.
