Okay, how cool is this? It's a 3-in-1 pen that's perfect for anyone who needs to write in the dark. Imagine waking up with a brilliant idea at 3 AM and being able to write it down without turning on the lights and waking everyone up. That's exactly what this pen is for! It's got an LED light right at the tip that illuminates exactly where you're writing. But wait, there's more - it's also a smooth-writing ballpoint pen with black ink (and comes with 4 extra refills), PLUS it has a capacitive stylus tip for using on your phone or tablet. The pen is made from aluminum alloy, so it's sturdy and has a nice weight to it - not like those flimsy plastic ones. To turn on the light, you just click the top four times (same to turn it off). It comes with replaceable batteries too. This 2-pack is perfect for night shift workers, truck drivers, students, or really anyone who finds themselves needing to write or take notes in low light. The red light is easy on the eyes and won't ruin your night vision. It's one of those 'why didn't I think of that?' products that you didn't know you needed but will wonder how you lived without!
