Accessorize your favorite cartridges with these stylish and sleek CCell 510 Thread Batteries. These pens are draw activated (no button!) and feature an LED light on the bottom that lights up when activated or plugged into a charger. Each battery comes in your choice of seven different colors and does not include a charger, just the 510 thread battery only. Be sure to grab up a charger as well; we have 3V chargers that will work perfectly for your needs.
