Hi everyone, I just received my new navy perforated calfskin med tote(I think so) today, I like it very much! But I have a question about the zipper, they use the lampo zippers(shown in the 1st pic), but I saw a smaller tote and a larger shopping bag(same collection) in NM, the zippers are another version of lampo(the hand-writing look ones), so they do use different zippers in a same collection of bags?Please help!!
