Eluxury says its 5.3 x 3.1....does that sound right? All the others are smaller (although still vary slightly in size). Here are the dimensions of some of the other:
Yeah it's a tiny bit bigger since it has to accomodate for the little pocket in the front where the color is visible. So I'd say the measurements are about right
Lol nothing,really. It's just for looks I guess. My mom has the Musette and has tried to put a few letters in it that she was ready to mail and the pocket isn't deep enough. So yeah lol just for looks.
