Christmas Tree Collar is a decorative covering for the base of your Christmas tree. It's usually made of fabric, metal, or wood, and comes in a variety of colors and designs. It's placed around the tree to hide the unsightly tree stand, and it also adds a festive touch to your tree. The collar can be used to hold presents or other decorations, and it can even be used to hide gifts underneath the tree. It's a fun and decorative way to add some extra Christmas flair to your tree.
