What's the oddest anime merchandise you own and what made you want to buy it?
My oddest - An 'oppai' mousepad. And not the one aimed towards women with some male character's cheeks as the pad. I'm referring to the one marketed to straight men.
True, probably not the oddest item to own. But it's not something that you'd suspect that I own. I received the mousepad as a bonus for buying sketches at the MangaGamer booth at AX in 2010. Since I bought several sketches, I have a couple of replacements

Originally, I had no intention of using it because it just wasn't my thing. But when my computer was set up a couple years ago, I found that I didn't have a mousepad. Knowing I still had the MangaGamer bonus items, I fished one of the pads out and tried it out. And you know what, I have to say that it's the best mousepad I've ever had. Super comfortable and great wrist support. To be quite honest, I can't imagine using anything else ever again.
