Glow in the Dark tumblers can be any color of paint. I add glow in the dark powders into the paint color then apply it to the cup. I can also add the glow in the dark powder to any style tumbler you choose to have. I also have glow in the dark glitter that comes in a few different colors. To make this cup glow in the dark all you need is natural sunlight or a reg. light bulb to hold it to. Natural sunlight does better and makes them glow brighter.
Only the speckles glow in the dark on the black cup. The unicorn glow in the dark is glitter that glows in the dark it was added in that last coat of epoxy.
Please Note All Tumblers take 2 to 4 weeks to complete.
