I don’t have a mini belt bag, so I am not sure. They also have a samorga for mini belt, but I don’t see the info on the dimensions on the samorga website. Before there were dimensions, I am sure about that. I just looked at my samorga receipt and it says W9.4 H6 D5.5 for my organizer. You can compare those numbers to mini belt dimenstions on Celine website.
