LP Glow in the Dark BlanketSnuggle up with our glow in the dark pajama blanket. Soft and sweet with a gentle glow on the LP lettering. Our glow in the dark print uses special pigments that absorb light and glow after exposure to natural or indoor light. To maintain its effect, wash inside out in cold water, avoid bleach and fabric softener, tumble dry low or hang to dry, and do not iron directly on the print. Recharge by placing the design under bright light before wearing.
