Outgoing Mail

When I was living in my country house, I could send mail from my mailbox at the gate by attaching a clip on the lid to inform the mail carrier that there is outgoing mail in the box.

Ever since the Post Office removed the outgoing mailbox from our street, I have been wondering if the clip would work here. I found out that yes, it does, and to my joy a couple postcards and a letter were picked up yesterday. Waiting to hear if they have arrived. :-)
