Crafted from a soft yet durable polycotton blend, this duvet cover and pillowcase set features a Disney Star Wars design that glows in the dark with your favourite characters printed onto it. Available in a choice of sizes, it is machine washable and tumble dryer friendly.To see the glow-in-the-dark effect at its best, this product should be exposed to either daylight or household lighting for at least 30 minutes before bedtime.  The effect will initially become more obvious as your eyes adjust to the dark. There will still be some visibility of the glow effect for at least 30 minutes after you switch the lights off.
