Evening Delight is a thermal/UV glow-in-the-dark dip with iridescent glitter. When indoors, this dip will change from pink when cold to yellow when hot. Once in UV light, it will change from a darker magenta when cold to a light purple when hot. Once in the dark, the dip will glow bright blue when hot and dark blue when cold. Evening Delight is like having six different colors in one dip!
