Very simple snap-together model kit of Optimus Prime. 
Has moveable arms, head and waist and a detatchable gun. The legs are fixed and unposable.
Its a pretty decent size and a great likeness of him.

It was carefully opened and assembled, but not displayed. I put it back in the packaging straight after i took these photos, so it's pretty much in mint condition, except for the packaging.

From an adult collector in a smoke and pet free home.
