Extra project stuff?

So, I bought the three caches with IP during this project event, and after that just ended up buying the big bundle with all three skins, 3 more caches, and a few more things. This resulted in me having three leftover project icons, and it kinda bothers me that they're just sitting there cluttering my inventory... is there anything I can do with them?

Also, kinda new here... how to you insert a picture? >.<

EDIT: Oh, I did it... I'm so cool \o/
