Personal Library Kit
Okay, this isn’t even letter related but I’m sure if you’re a lover of letters you’re also probably a lover of books, because the written word is great! I stumbled across this Personal Library Kit awhile back and was immediately overcome with consumerism want. Pockets, checkout cards, a date stamp, and even a pencil, my personal favorite writing utensil of choice (side note: I even own multiple pencil sharpeners, including a manual mounted crank sharpener like the ones in elementary schools).
Anyway, I’m classifying this under Mail Art with the excuse that you could TOTALLY use this for your mail art purposes! Who doesn’t want a library themed letter? Raise your hand if you do NOT want one!
No one is raising their hand? THAT’S WHAT I THOUGHT I MEAN I AM JUST SAYING.
By the way, when I was a little kid, I totally ran a library out of my room. I figured I had so many books, who wouldn’t want to come to my library? I didn’t have this nifty set so I wrote who check out my books in pencil on the inside cover. Also, my mom was the only one who came to check out a book. Kind of sad now that I’m thinking about it.
(Disclaimer: I still make no money off Going Postal, including this link. I just did a search for “library kit” and posted the Amazon link because it’s pretty ubiquitous. I also don’t own this (YET) so I can’t speak for the quality or anything.)
P.S. I will not say no if you want to send me one for trial purposes, Knock Knock Marketing Team. Also you can feel free to send me pretty much anything on your site. Thanks in advance!

That is adorable. I miss my old library. My husband is amazed how often I dream about it and its wonderful old wooden card catalogs. Wonder whatever became of those….
