Rounding out our examples of the charming wares available for students (and others) at Archie McPhee is The Ultimate Geek Pen. “Ultimate” is a subjective word, but this does include a pen, laser pointer light, flashlight, and UV light. So, it’s “Ultimate” in the sense that, if you need light waves for a task, you’ll probably be covered. Batteries included; nerdy impulse to use the pen for writing Tesla-esque theorems in invisible ink not included; user must provide. Mcphee.com.
