Monteverde Quadro 4-in-1 Multifunction Pen Black
The Quadro from Monteverde is a really stylish multifunction pen. Its metal barrel, crafted from solid brass, features a knurled grip area, sprung pocket clip, and a timeless satin finish. The barrel band is inscribed with 'Monteverde Quadro'.
Inside there are 3 ballpoint refills in black, blue, and red, and a 0.5mm mechanical pencil. Hidden underneath the push button is a replaceable eraser.
Advancing each refill employs a gravity-assisted mechanism: simply hold the pen at a 45° angle and rotate until the desired refill is face-up, then click the push button. To retract, press the thumb switch located on the clip.
