Hi. I got some USA forever stamps. I want to send to Tony Bennett, the address is in the USA (the address in the database). How many forever stamps do I need to include if I want a reply? Oh and by the way I live in Ireland.
(Sorry for asking stupid questions, I have never used forever stamps before lol)

I'm in the US and when I send over seas I usually put 6-7 stamps on the 8x11 photos

How big is the item you are sending, and how much does it weigh
