Found this sub a while back, and decided to give it a shot with RStudio! Filled up a contact form here and they sent them over free of charge https://www.rstudio.com/about/contact-sales/ I love the R community :'-)

No no, as long as it’s the envelope within an envelope, you’re fine. Like this. You’ll be able to send it just fine like any other mail,

Your post just sounded like maybe you were trying to put the envelope you addressed to yourself in the mailbox by itself to send, so I wanted to make sure that wasn’t the case!

It was a gift from my dad. He bought it on Amazon (free to me lol)
