A fast and easy way to bind books, this 2 piece set pushes together and no special tools are needed.  Punch holes with an ordinary 1/4" round hand held hole punch, push the cup portion of the book post through the holes in your stack of paper and then push the screw portion of the book post into the cup. That's all there is to it!

Each book post is approximately 3/8" deep and will hold 12 - 20 sheets of paper, depending on the weight of the paper.  Use one set of book posts to make a cool "swing open" book.  Use two or more sets of book posts to create a more traditional style of binding.  You can change the color of your books posts by painting them with nail polish.  Yep, that's right - nail polish. Go figure, huh?
Nail polish works and won't chip or peel off the book post.
