HappyHapi Book Ends Sturdy Bookends for Shelves, Universal Book End Heavy-Duty, Nonskid Metal Bookend, Premium Book Holder for Office/Home/Class/Library, 6.5 X 5.7 X 4.9 in (4 Pcs/2 Pair, Black)

These work well, are sturdy, plus, they have a hole in the base, as pictured, to secure them to a shelf if needed. I added mouldings to my shelves, so, when the bracket is pressed against it, it is going no where except during an earth quake or something. The bracket is holding about six feet of books up straight.If using the screw, I would keep it to the outside of the book stack, as pictured, to keep the book level, especially a soft cover and to avoid a screw rusting against a book because the paper had acid in it.The listing shows bright white, they are more an almond or antique white, white is the vertical metal shelf system and the so far unpainted PVC moulding trim. Which are not BRIGHT white like the paint used on the wall behind the shelves. Though I was a tad disappointed that the brackets where not a true white, as shown on the listing, someone else will likely be happy theirs was that color or would not notice at all. My wife did not notice the color difference and did not care what color they are.imho, So, nothing worth deducting a star, just showing it in case someone is truly set on a bright white bracket. I liked these so much, I ordered a second set and I am likely to order a 3rd, if that means anything. Just glad to have them and my wife is even happier because it's her library I made.

They work well. Don't slide around easy. Hold heavy, tall books well. I've bought the black ones in the past that have held up well. I ordered thebwhite ones this time to blend in with white shelves. If you're a crafty person, you can easily make covers to go over them.

Sturdy, work well

Slim; effective; reasonably priced. I use it to display books....duh!

For the money, a good buy - sturdy for medium sized books or smaller

Very pleased with these. They are just the right weight to control my books.

These bookends are effective for keeping our long bookshelves organized.

This set of bookends worked great and the price was very reasonable

Sencillos y resistentes. Comprelos.

Son sencillos, simples y funcionales, sirven para lo que son. No tiene diseño alguno por lo que no son decorativos pero se ven bastante bien y hasta llegan a no verse.
