Well you guys already know alot of mine, but...
I use nail polish
I prefer older music to most modern music (Most of my favorite songs are from sometime between the 1940s and 1980s)
In addition to the old music thing, I have a huge thing for antiques (Especially from the same eras as the music I like) (It sorta runs in my family, my mother is also an antique maniac, and so was my grandmother, and my great grandmother, and so on and so forth)
I guess im always kinda obsessing about my hair and its style
I prefer english bacon to american in many (but not all) cases
I sit down to pee and almost never use public toilets
and probably some more I might remember later
models are expensive as hell though. BUT HAVE FUN.
3,000 yen is like 20 US dollars
