These bookends are unfortunately garbage. They are very cute but they are way too light to withstand any real amount of weight. Kind of dumb since books obviously have some weight to them. I got these for my daughter's nursery and she has about 10-15 Dr.Seuss sized books and these don't do a great job. If the books lose their balance, these bookends do nothing to stop them from falling over. I wish I would've returned these when I got them.
