King Size wheel stickers! Basically you put them on your wheels and get an instant set of graphic wheels, without much cost or effort. I'm gonna have to pick up a set soon and put them on the back of my winklers (I always love wheel graphics going inwards) - they're pictured on a set of King Size wheels but I think they should fit on most. Nonetheless, at only 3 euros for 6 stickers.. Bargain for the effort it takes to make these!
Go check these on King Size (and other sticker packs too) here :)
