I let my sister use my cube and she dropped it, it fell right on the corner, now those 2 pieces have that whitening on the sides. it doesn't change anything about the turning but I don't liked it, specially since it's a brand new cube. Can someone help me? is this possible to repair? if not I'll make her find a replacement for that piece or buy me a new one. It's a Super rs3m ball-core
