A steam key is basically a license / code of a game (Mine are most likely indie games valued at around $0.5 to $5) which you can redeem at your steam application which will provide you with a game. for example you purchase 50 keys you will be provided with 50 keys in the following format
3D Tower | HY8WA-KCNXZ-5GIJJ
(Yes this is actually a working code)
I asked for a vouch copy (steam keys), He was quick replying and provided a key which worked. Throughout our chat he was prompt and very professional, Will do business with the user again. If you need steam keys he is your guy.
Asked for one of the vouch copy steam keys and he immediately sent me it. He helped me even claim the key. Professional and very helpful! If you need a guy, relating to stream keys, I recommend going to him. I highly recommend it.
