I bought my first pair of circle lenses last year in Ayuthaya's shopping mall (Thailand), they were jet black and 15 mm (Dueba brand). I thought they were lovely and I wore them until I couldn't (which was...about 4 months I think?). I actually still have them somewhere.. After that I bought Dolly black and Max Gold Brown, which were both 14.5 mm. For some reason in the past month I have gotten into some kind of circle lense frenzy. Maybe because of the beautiful Mimi series...? So I ordered Princess Mimi Almond and Sesame Grey, Mimi Café Waffle Grey, Super Pinky green and Forest (Xtra) Blue this month, I think they are all 15 mm (...?).
