Knock Knock personal library kit

Thing I hate: lending out books to people who don't read them. Thing I freaking despise: lending out books to people who don't read them and also don't return them RRRRR!! :P This kit will make sure that those slackers know they have your book, and you remember who you lent them out to. Also keeps your library in order. What a pro!
