Ever had trouble seeing your position markers on a dark stage? A Japanese company has created a solution called the Luminlay.
Available in green or blue, the Luminlay is a highly luminous material that you inlay into the side of your neck where you want your markers. The material is then charged in seconds by an LED flashlight (also available from Luminlay), and you are set to play in any limited light situation.
Luminlay was created as an alternative to installing LED lights in the neck, which requires a battery.
The Luminlay goes for 1800JPY (Japanese Yen), which is roughly $20.00 USD. Visit Luminlay online for more information at their web site.
