sorry, but i can't find your post! i got my mouse stam today and had the same problem! i kept trying to open it with all my force and it wouldn't open! so frustrating! but my husband figured out a trick to open it and now it's super easy! with the front of the bag facing you (zipper pocket in front), put your thumb on the bottom of the left circle clasp and the index finger on the top of the right circle clasp. now twist your two fingers in a clockwise manner and the thing should open easily. does that make any sense? i hope it does!
