Just what i needed on my open bookshelves!  You can't even see them on the end of most of the books!  Love them!  They hold up some heavy books!  I actually came back and bought several more sets, I love them so much for stability. I have pretty things on the ends, but some aren't good at holding the books up, so i put these at the end of the books and put my pretty decorative pieces on top of the ends of these and you can't even see them there! I love them! In the picture it's behind the hourglass.
