These shelves arrived SO fast! I absolutely love them! So easy to install. They come with 3 different sets of (easy to understand) instructions and 2 different types of anchors and screws, depending on what your wall is made of and how you plan to install them. They do stick out from the wall a little wider than I anticipated, so be sure to check your measurements. They are made of pressed wood but the bracket is metal and seems like the shelves will support quite a bit of weight. Great buy!
