Battery, bulb and refill are all easily replaced and only the refill is unique to the pen. Each pen comes in a faux-wood grain presentation box. A great gift. Comes in Red, Green and Amber. Choose either flashing or steady.
Steady marker is great for downstage center and quarter marks.
Excellent for dancers. Light booms, etc . An economy priced laser that really delivers. It's powered by 2 AAA batteries. Turn it on by pressing the button on the side of the barrel.
