I would like to clarify, this is my friends inventory, I am posting on his behalf, and as I stated before, the first trade is for one skin, this is to verify that A) you will actually pay for the skin and B) so you know were not ripping you off. After the first trade you can request more than one skin at a time.
If it helps at all, he has about 250 of my skins that I gave to him to bet, so yea, I trust him.
Let me know if you're still interested, he still wants to sell them.
