With your personal library you have to sometimes keep everything in its place and these bookends may be just what you need. Made of cast aluminum, brass and iron. These are PENDULUX Rocket Bookends, as if split by a wormhole, the two solid cast polished aluminum halves of the Rocket Bookends can hold an infinite mass of knowledge between them. Heavy iron bases and soft felt bottoms keep planetary sagas secure without scratching shelves, while the brass antenna and portholes allow unseen passengers to look out over your personal library. If you love and want then go HERE to get.
