I want to sell my old Nintendo ds i?

I want to sell my old Nintendo ds i, to Game Stop, for $50 but I threw the box for my ds i away, like a few months ago. Will I still be able to sell it to Game Stop without the box?
(Oh, and by the way, I need to save up money for the new i phone that comes out this summer… Hopefully, I will have enough money to buy the iPhone 5s for my birthday in June.)
