Unicron.com figure stands come as shown in the picture to the right.  Each package includes the following items, seen laid out clearly in the picture at the bottom of this page.

A stand base, a short clear (polycarbonate) stand pole, a long clear stand pole, a black stand pole (made of a more rigid 'glass filled nylon' material) and a stand top.

Why the black stand pole?
Unfortunately, the Armada Unicron figure is SO big and SO heavy that it does not work with the long clear one (due to it being slightly flexible.)  The clear polycarbonate stand pole is actually strong enough to hold even Tidal Wave in his combined starship mode, but to uses this stand with Unicron requires the black pole, AND it must be permanently secured with super glue.  See Stand Instructions for more details on this.
