G.M.
I know this is a late answer, but I read your request when you first posted it, and today I was at TJ Maxx and saw some mario school supplies. One was a school supply kit that had a folder, pencils, pencil bag and a bunch of other fun stuff. I think I also saw a lunch bag with mario too. It was at the TJ Maxx by the fairfield commons mall in beavercreek. Not sure if you live close to there or not. TJ Maxx's sometimes will carry the same stuff at different stores, but you never know with them. Just thought I'd mention it if you were still looking for some. Good Luck.
