I have a new Alma, it has a lock and 2 keys on the zipper - I don't quite know what I'm supposed to do with all of this - do I remove any of it? Also, does it matter where you zip it? all on one side or in the middle or is it completely unimportant? I feel there is something I should know about this - It's my first LV with the lock and keys. Thanks for humoring me !!
