Found these at Bristol's Cribb Causeway The Mall store.
Was priced up as 1p - wasn't a reduced sticker just a regular one.
I believe they are for either the PSP phat models or slim and lite/brite versions. Bought one for myself and another for a friend.
I know the PSP is dieing out but for 1p why the devil not?
They are much comfier to hold than the generic ones on Ebay.
