A hinged Christmas tree is a type of artificial tree that has individual branches that are hinged together, allowing for easy assembly and storage. The branches are attached to the trunk in such a way that they can be folded up or down, making it easy to transport and store when not in use. This type of tree is often popular because it provides a more realistic-looking tree while still being convenient to put together. It also tends to be more expensive than a non-hinged artificial tree.
