Just a thought on the small puzzle tote, my daughter has a Prada small tote (same basic idea). She bought an insert that acts as a closure for the tote. I think she bought it on Etsy. It makes her tote totally secure. I bet there is one that would fit the Puzzle tote and make that more secure.I love it but I don’t love the fact that it’s open all of time. Pretty easy to reach in and take something?
