[H] 1 CS:GO key [W] Blade Symphony

I can do 1 key for a 2-pack opening. You open my 2-pack for 1 key and you give me the extra copy back. I also require a collateral of one extra key that I will give back with the copy you give back to me.

i can do for 1 k + 2 ref , if you still need it please add me :)
