You need to see the video to really see these babies in action.
The spines are 3D printed out of clear PLA onto fabric mesh, then the lights are inserted and the whole thing is stitched into the leather bracer. Each bracer has a battery pack pocket that straps around the upper arm just above the elbow.
Each battery pack takes 3 AA batteries that last up to 16 hours or more on full. The bracers have a remote that allows you to change the colors of the lights from cool white through the rainbow of colors. The lights can be programmed to flash, fade, strobe, and fast switch.
The bracers lace up on the side with stretchy bungee cord. The body of the bracer and the panel under the lacing is all leather.
These are a size medium or a 6-8 inch wrist with 8-9.5 inches around the whole hand at the knuckles. The bungee lace-up closure makes this a very adjustable design.
These are sold as a Pair. The price is for both bracers. This is currently the only pair available in this style.
