I bought a Chloe Drew from Vestiarie a few weeks back and noticed that my lock (where the pin sits) doesn't move from being horizontal. The clasp opens up fine but I was confused as I thought it rotated? I've seen some people with their clasps being vertical too. The bag came with all the usual authentication stuff and has a card to register the bag online with Chloe, which I've done, but can someone put my mind at rest about whether the lock is supposed to rotate or if it's static on some versions?
