Any kind of doujinshi item you can think of, there's a Naruto one. I've seen mousepads, stamps, stickers, clearfiles, calendars, shitajiki, fans, mugs, stationery sheets, postcards, cosplay items, badges, telephone cards, bookmarks, a PC Game for crying out loud! Of course, probably the most incredible things are the full tarot card set, including both the major and minor arcanas, made by lots of circles working together. They're incredibly good quality. I plan on uploading the ones I own and a list of the others..

Circle : Kujira, RII System & mitcheyHOUSE Published : ?? Size : A5 Comments : I bought this thinking it was stationery, but it's actually a notebook. There's two comics running along the top and bottom of it. On one page is a panel on the top, and on the next page is a panel on the bottom, of the second comic. They're pretty cute, one's about Naruto's birthday, the other's about Naruto and Sasuke's friendship disguised as a rivalry.

Circle : Jidou Tengoku & (Unknown) Published : ?? Size : B5 Comments : This is a cardboard cut-out box for holding Naruto doujinshi "trump" cards. I haven't assembled mine because I keep them in a bigger and sturdier box, but I love the picture of the three girls. ^_^
