Great bag. Only, as I suspected, for me a small pen. I wear bags over my shoulder. She sits on her shoulder, but right under the armpit. And for me it is not convenient. Although I have the size m and I'm thin. But I still liked the bag very much. Plump. The bottom does not fail. So you can both for documentation and anything in the store to buy. It won't get wet. Inside is some oilcloth and or plastic. I can't understand. It is dense and flexible. Good to touch. I tried to take a picture of it. It just wrote a supplement. And in general, everything, as described in the reviews.
