Glow in the dark design:
Glow in the dark ink is a two-part ink process. First, a layer of white ink is screen printed to create an excellent bright base for the glow in the dark ink to be applied to. Once that layer is dried, a special high-intensity glow in the dark ink is applied. Glow in the dark Ink is machine washable and should outlast the lifetime of the shirt. Once you are ready for your shirt to glow, charge it under fluorescent lighting before heading out on your Sleepover Safari!
