Penguins are very cool. A penguin clip for books and putting together packets and papers. Extremely easy to print. The left version makes it easier to clip while the penguin is facing left, while the right version makes it easier to clip while the penguin is facing right. This is because of the slant on the clip which makes it easier to clip and not damage the paper. You can print crazy amounts of this in a really short timespan, so try printing a bunch for your books!
