Thanks to you ladies and gents, I have been able to find two authentic MOCA Neverfulls. The seller I have been talking to has offered me either size for the same price-one (the mm) is brand new and the gm has been used once by her sister who felt it was too big. I am a big bag person, but is the GM too big? I hate small bags, but when a bag is too big I feel stupid. Any suggestions? MM or GM?
