Thanks for the replies! I had a midterm today so couldn't reply before now. None of them are the exact same as the one he has, but the same idea. Freedom's Pouch looks amazing! I'm definitely going to order this one, probably once I'm done doing some browsing.
edit: Anyone have a link to the Freedom Pouch? I could only find a Japanese link and I don't understand Japanese so I can't purchase from the website.
