The price figures as they are £5.50 ($11) in the UK, the Brits mostly just swop the $ sign for the £ sign. I just thought they looked a convenient and simple way to apply a paint in a spray form. If anyone has used them and found they just don't do the job that well it would save me the bother of another purchase from the UK. A handy accessory though, I can think of a lot of uses for this thing.
Cheers.
