Opening Space Engineers 4-pack for 2 TF2/CSGO keys each 4-pack + collateral

Requirements:

1) 2 TF2/CSGO keys and 16 keys as a collateral for each of the 4 pack (I may also take other steam gift games you may have as collateral)

2) If you have excellent trading rep history with lots of reps AND a respectable Steam account I may do it without collateral, but I reserve the right to decide so.

3) You CANNOT already have Space Engineers in your Steam library

4) You MUST have bought something from steam store more than 30 days ago, or the extra copies will become non-tradable You are able to unpack the 4-pack, it will show like this http://i.imgur.com/odUbPpE.jpg (Picture found in the internet) If it shows like this http://i.imgur.com/nXTCSbt.jpg, the extra copies will not be trade-able How does it work?

1) I will give you Space Engineers 4-pack gift and you give me 16 keys per each 4-pack as a collateral

2) You then activate the 4-pack in your inventory, and soon after will receive the 3 extra gift copies of the games in your library

3) Finally you will trade me those 3 copies and I will give back your 17 keys from collateral
