We featured these Glow In The Dark Duvet covers at B&M a while ago when they were first launched, and they were extremely popular. Now B&M have started selling them again, and they also have new Double Duvet Covers to match.
The covers come in either black or pink, and the single size is £9.99, while the new double size is £14.99.
They are a polyester and cotton mix and it's the stars on the duvet cover that glow in the dark. I can see that these would be a good idea for children who need reassurance at night time, and they look really lovely.
B&M don't offer online shopping but they are in stores subject to availability, and their website advises contacting your local store to check stocks.
