Sounds like "male box"

This week's MonoMonday challenge is entitled 'Mail box' hosted by Rainie.

I don't have a mail box, I have a letter box and when I post anything I use the post box. When I need a photograph of a mail box then I'm going to have to improvise. This is a box, it has a stamp on it so it is mail, and the intended recipient is a male pogonophiliac. The photograph is in mono so at least that can't be disputed.

It is not intended for those who have pogonophobia.
