Are these legit convertible kenny brown's? I'm a bit skeptical with ebay, but if anyone owns them could you assure me that these arent some cheap knock-off's!?

i would be a little skeptical of anyone on ebay that accepts payment via moneygram or western union

well you can pay by paypal, and with e-bay theres a guarantee, i'm not concerned about getting jacked, especially with the dude's feedback and history, i just want to make sure they're REAL double diamonds and not cheapo look-alikes
