This is the perfect size!  Large enough to hold a day's mail and easy to reach into. There is only one hole at the top to hang it and it works well on a command hook.  It has no sharp edges and is nicely finished.  There is a loop if you'd like to add a small lock.  I love the look of this at my front door and my mail carrier is looking forward to the convenience of using it for mail on days he has packages to drop off on the porch, rather than making an additional stop at the box at the end of the lane.
