Did MJ ever use a Lampo zipper in the bag?
It depends on the bag. Some come with Lampo, but most have riri. I'm not entirely sure about the Sophia bag...perhaps the limited edition Sophias had lampo.
aside from the fact you asked this question in 5 different places you still didn't provide basic info that was asked. We need to know when the bag was purchased. Ltd. Edition Stellas from Fall 05 had Lampo zippers. They had the brass buckles and hardware.
(eta: I'm not being snippy, but 5 places for this question???)
