Oh my goodness. These are going to be on every unicorn fan's wishlist - you can now buy Glow In The Dark Unicorn Wall Stickers! They're just £5.58 a pack from Amazon seller Ufingo.
You get a sheet of 10 glow in the dark unicorns in each pack, and they will attach to any clean, dry and flat surface so can be used on furniture as well as walls. They're easy to apply as you just peel and stick wherever you want them.
Reviews are a little mixed, but how well they stick will depend on the wall surface, as they are designed to be removable and not leave residue so will not be completely adhesive on all surfaces for that reason.
If in doubt you could try them on furniture rather than walls - my son has a Mario themed wardrobe as the stickers didn't work with his wallpaper!
I think for just over a fiver these are well worth a try for a unicorn fan, and could be the prefect finishing touch to a unicorn themed room.
