I want a black epi hand bag that is large enuf for work and casual use. I'm giving up on epi speedy 25 due to it's opening. I did try on black passy pm and loved it but bothered by the open top and smooth leather(? easily scratched). I think montaigne sac's opening more secure from the thicker strap. This would be my first hand held bag and I would prefer a more secure opening. I do favor montaigne sac a bit more since there's the shoulder strap option and prices are similar. But I forgot to try it on in the store and not able to go back due to distance. I don't have enough $ to get both so please choose one and tell me why. Thanks.
