This tree stand is made from high quality green plastic, perfect for the holiday season.  It has an easy fill port and holds a good supply of water so you don't need to fill it too often.  The tree is held in very stable fashion because there are two groups of four braces which allow you to make the tree straight very easily.  This was only used one year.  It is clean with only a slight residue of pine resin on the bottom of the reservoir.  The outer diameter is 24 inches and the height is 9.5 inches.
