Good set, it contains several covers. The reason I took a star off the five star rating is that the hole saw that came with it wasn't long enough to cut through my table. It was also very difficult to try and assemble. I managed to collect it. I have a hole saw set that comes in almost every size imaginable and luckily I ended up the same size as the hole saw that came with it. I was able to drill through the rest with a hole saw from my other set. But the upper part after pasting turned out to be excellent. Happy with the result. The cap works great and stays in place and looks as professional on my desk as it did.
