The blanket glows in the dark, it’s mysterious and interesting. The longer the blanket is exposed to a bright light source or sunlight, the stronger it glows in the dark and the longer it will last. The light from the blanket will not affect the children's sleep and will make them feel safer when they fall asleep. Super soft for a cosy bedtime, this cuddly blanket not only keeps you toasty but glows in the dark too! Snuggle up under a blanket of glowing stars and make bedtime magical!
