Help identifying gift

Hello fellow steamgifters! Recently i won my first game here - The Ship Complete Pack, i activated it (received gift) and everything is fine. But then i noticed i have something in my steam inventory - The Ship Gift. I won only one copy of the game and activated it. Is this some guest demo version, or full game which i can use somehow (like gifting to someone here - if it won't consider regifting). Sorry if it's a stupid question - i've never dealt with inventory, and didn't find definite answer in google.

Here is a screen of my inventory.

Thanks ^,..,^

UPDATE: My giveaway of this game here
