This matte gold-plated bookmark is perfect for marking your place–and leaving your mark. When it's not keeping your spot in that great American novel you're reading, you can stencil 'I Am Your Ruler' wherever you see fit (except in those library books, you literary badass). Bonus: there's also a 5.5" long ruler etched into the surface, so you'll always know if nearby hedgehogs are tall enough to ride any rodent-based theme park rides.
