One is a multi curve front plate the second is a single curve back plate. I bought these plates a few months ago but I want to get something different now. They've been in my plate carrier the whole time. They haven't been dropped or damaged. You'll notice that there is duct tape on one of the plates. The "carbon fiber" wrap got a little nicked so I put the gorilla glue duct tape on it. Other than that the plates are brand new. If you were to buy them from armour wear's website it would cost $320. I'm selling mine as a pair for $220. Located in the Lake Charles area.
