They probably cost about 20p to manufacture.
I'm gonna start cutting out my own pieces and dunking them in tippex, then flog em for $50
I'm only gonna make 10 mind...so they're rare, therefore really worth more like $500, but I won't rip you off
yeah, well ill be gettin a pair as soon as i can find somewhere that ships them... but they'll prob be out of fasion by that time, so ill just have them as 'retro' kit...
