Unused Project Cores, Project icons etc.

So i was thinking, i have bought only 3 of thoose PROJECT cases (Ashe, Kata and Ekko). I was abroad when Riot realised the last case, the yellow one, and i didnt get it in time and now i have unused 5 PROJECT cores and Ashe, Ekko and Kata Icons and on tp of all that i didnt get a project skin. So i was wondering...will you Riot place again in the store the chests so we can get them again or I will have them in my inventory for the rest of my life? Thx
