Combines a refillable ball point pen with a red LED light to illuminate your writing in the dark while preserving your dark adaptation while observing. Push the button on top to turn on the light, and twist the barrel to use the pen (no cap to lose in the dark). You can also twist off the cap and use it as a red flashlight! Elegant silver trim (lower half is transparent but appears red in the photo since the red LED is on). Comes in an elegant plastic case. Makes a great gift too.
Batteries and one extra pen refill included. Size 4-1/2" x 5/8".
