Hey it's my label YEAH!!!
but like badchad said it's much easier to do it rectagular, and afterall once you've print it you can do whatever you want with it. For paper I use normal sticky paper, it's not glossy but it works perfectly fine. If you want a label ask me I could do one, just tell me if you want an original or custom. And BTW that label of zelda 2 just like zelda 1 look's a lot better on a grey cartridge.
