The first set arrived both broken (The anchor and the wheel are only SLIGHTLY connected to the bookends.... they must have broken easily during shipping.    I received another set, and I'm positive these will break soon enough.   They need to be secured WAY more to the actual bookends...a little pressure and they will snap right off.    I've ordered tons of things from Wayfair, this is the first product in which I was disappointed with the quality

Cons: Poor quality.
