Backpack
 

I was wondering how long a CS item stays in your backpack. Does it stay there for the time the item lasts (like 7 days) or does it stay there until you take it out.

I wanna know this cause I want to buy the elf set, but I can't play for the upcoming weeks and seeing they're only gonna be there a limited time.

I hope someone knows the answer ^^

it'll stay in your backpack until you activate it (right click). THEN it goes to your regular inventory. Even then, the timer doesn't start until you equip the item. In fact, it will ask you if you are sure you want to use it. It's pretty clear cut

I just wanted to be sure ^^

Thanks for the info!
