WTB iphone 4/3GS brand new original white earpiece

[Jiean2004]

Hi,I assumed many of you do not use the iphone 4 or 3gs original white earpiece(with mic and volume control) that comes along in the packaging and it maybe collecting dust....Why not benefit me by selling it to me as mine is spoiled due to some mishandling during my cycling trip(And it was the second incident!!  )
I am willing to buy at max price of $15 bucks....(that was the price I got my last original brand new piece from online)
Self collect or to your place of convenient, thanks
