Really good work. You had perfectly understood our needs.
This shopping-bag is a master piece of elegance. I think the #28 is the more comprehensive logo for end users, but I love the originality and colors of the #50.
Forget #49 I don't like the P or M on the bag. Maybe a little white puzzle in replacement of P ?
We love reflections on the text of #79 Could you adapt this logo and change the colors to black&orange ? (you can use a blue piece in the bag instead of the orange one)
I think the "Presta" word is too light in the top section. Could you darken the orange gradient please ? Also, I would like to see the handle in orange, instead of black.
