I bought these last year and have only worn them a few times. I probably haven't worn them even five times. Maybe I wore them three times, and that was for commuting to school. So, they're incredibly clean. However, on the inside of the outer side, there are three characters written in katakana with a magic marker. They're probably written in black marker on a gray background, so they're not very noticeable, even if you try to cover them up. I will ship them as they are.
