Hi, If you have any ideas yourself, send a message to sir. I'm sure if the idea is good enough they could feasibly consider it and get your concept on to some sort of clothing.

As for things with your own Tori, or custom work in general, I wouldn't count on it. Unless there is an option through Teespring to get a "blank canvas" and just upload an image, then sure, but I very highly doubt it. But then that's not really Nabi's merch is it then?
