Just before I purchased these 3 I bought 2 sets of 2 larger ones. The color is exactly what I was needing. They are packaged together so no scratches or damage. My husband (the installer) says they are easy enough to install. They are perfect for a diy update, durable and hold plenty of weight for their size. Happy happy customer
