The Q4 Quad-Action Space Pen is the best of all worlds, featuring black ink, red ink, a .7mm Pencil (with eraser under cap), and a hard plastic stylus all in one pen! Just rotate the pen so the color that you want to use is facing up, click, and you're ready to write! It could very well prove to be the only pen you'll need. Please note that if you don't have much use for the hard plastic stylus it can always be replaced with a purchased Fisher Pressurized Universal Refill, allowing for the additional option of blue ink.
