Hi everyone - I have been lurking over here, and am now seriously considering a paddington. I have you all to thank! My question(s) are this: Do you find these bags really heavy? (I own Balenicaga) And, as I have never seen a paddington in real life - how does that lock thing work? (sorry for stupid question) Do you have to unlock it everytime you get into the bag, or does it just kind of fold over to help keep it closed while still being open? Thanks for your time everyone and can't wait to hear from you!
