It comes in 2.5", 4" and 6" long rods, and what I bought is the 4".
If you have all the sizes, you can combine them to pose even figures.
It is meant to pose flying vehicles of any scale, providing you have the appropriate rod length. The base is thick & has a heft to it, and it also have rubber nub underneath the base for extra grip & stability.
