Got one of these which came with my black G3 and I just don't want it lol, have ordered a black one instead.
This one hasn't been heavily used and only shows the very lightest of wear on the back. Essentially not even anything worth mentioning but I always do so for posterity! Comes boxed, is a genuine original and has the LG hologram on the packaging. This is the one that replaces your back cover btw, not one that clips on top of it.
Just looking for £10 plus postage, £2.50 should cover it for 1st Class Signed For.
