This promotional item comes in various forms. The slightly common one in the market carries a switch where the EL plate would light up when switched on. The other one would be the Sound Activated T-shirt. This promotional product is especially good for concerts as the LED plate on your shirt would light up according to the music in the background!
EL Plate can be attached to the Shirt in 2 ways, either by Velcro or Sewing. However, do note the Velcro ones can be detached from the shirt, allowing it to be washed by hand or the washing machine. However, the one that is sewn onto it can only be hand washed.
