Lead holder contains eight colors: Diazo non copy, PPC non copy, red, blue, brown, orange, yellow, and green. Diazo non copy lead will not show up when copied by a Diazo (wet type) copy machine, and the PPC non copy lead will not show up when copied by a PPC (dry type) copy machine. Most modern copy machines are PPC. However, blueprints are still often copied by Diazo copy machines. Additional refill colors available separately.
The Pentel Multi 8 lead holder contains eight different colors of 2 mm lead in one convenient holder! Perfect for a designer or artist, this lead holder allows you to move from one color to another with ease - simply twist the plastic clip of the holder to point at the color you want, then press the top knock button to release the lead, and extend it from the lead holder tip. The lightweight plastic holder has a ridged grip area and a balanced feel in hand.
To refill the holder, turn the top knob so that the silver line is aligned with the black plastic arrow on top of the clip. This will then completely release the lead when the top button is pressed down. Keep the button pressed down, and the clutch claw at the tip opened, so that you can insert your refill lead through the holder tip. Once your lead is refilled, turn the knob again so that the line is not matched up with the black arrow, so that the holder will catch the lead at the metal end.
Lead holder dimensions: Approximately 5.5 inches (14 cm) long, and no wider than 0.5 inches (13 mm) in diameter.
