This is an apron purchased from Gakken's "Suteki na Sensei" (Wonderful Teachers) shop! It is a used item. ○ Size: M-L I didn't find any major stains, but please understand that I may have missed some dirt as I am a non-professional inspector. Also, there are some pills because it has been worn several times. Furthermore, it has been stored at home, so please refrain from purchasing if you are concerned.
