These stands are great for decorating your Christmas tree because you can rotate them around without having to stop and move you or your decorations. Also they are great because they allow a full 360 view of your tree form any angle. So you like one side better than the other or if you purposely decorated one side differently, you can display it with just a simply turn.
These stands can be used for real or artificial trees. They can also fit a variety of sizes.
