So I made a template of the standard diamond shape for all the division insignias in Bleach, printed them out en masse on cardstock, and mod-podge'd them to black craft foam. Then I half-assedly sharpied the kanji onto them. Most of them look OK, at least.
So I don't run out of magnets, I'll be putting the magnets on the back of these only when someone buys one. That way I won't waste valuable magnets on designs that won't sell. So if you buy one, I'll need five minutes or less to glue the magnet one.
I realize that some divisions are significantly more popular in the fanbase (10, 6, 3, 5, etc), so I'm bringing a bunch of blank magnet fronts with no kanji on them and I'll put the number on at request. I just thought it was important to do all 13 for display's sake.
