Duncan - Blue LED Light Up Counterweight
This is the light up counterweight that comes with the amazing new light up Freehand Zero!
It glows with bright blue LED that turn on or off by pressing a small button on the side. In the dark it makes your yo-yo tricks look like magic!
Make sure you check out the YoYoExpert Counterweight instructional section to learn tricks and for help attaching it to your yo-yo string.
Note: Batteries cannot be replaced in these but they do last a very long time and still function great as a clear counterweight after.
