I don't know if you guys can help me but I'm building my own mailbox, and with me being disabled, I can't be making needless trips 1/8 mile away to an empty mailboxSo what I can't figure out is, how to fix it so it will show on the back of the box, that the mail person has been in there delivering mail.
My mind comes to a freeze on this, it can be real small or any size cause I have a telescopic lense I can look thru to see it.
I'm making it 8" high by 10" wide by 20" long which is close to what the old one was.
So if anybody has any ideas I'd appreciate any suggestions
Thank you in advance
