Hi gang. Looking at a local pair of matte rootbeer/tungsten PB1's for a good price, but a couple things caught my eye as fishy. 1) "P" sticker instead of "H": 2) The yellow lines on the inside of the arm hinges: I'm pretty sure he's worn them a couple times (they seem to be in great shape though) and just stuck a "P" sticker on to sell them, but the yellow lines are throwing me off. Are these normal? Thanks.
