Nite Glow Powder
Nite Glow is our 15-minute glow-in-the-dark powder. It is whitish in shade with a familiar greenish glow. When we leave at the end of the day, it is our little box of Nite Glow which lights our way out the door.
Nite Glow may be used for all kinds of interesting projects. In soap and gel candles, use it to color embeds. It can be added to nail polish, potpourri, face paint for novelty projects. You can also add it to translucent painting mediums and paint your craft projects.
