Bay Burst Metal Gyro Launcher

My son was super excited to get these Christmas morning, but I was dismayed to learn they are knock offs. They come with teeny weeny stickers and no instructions on where to put them. After scouring the Internet, I asked my son if he was okay playing without the stickers. He said yes, so we left it at that. They are cool looking and he loves them, though, so I guess all is good.
