These are plastic 25mm miniatures from Games Workshop's Lord of the Rings line. They are the Fellowship models from the Mines of Moria boxed set which was released in 2005.
These are pre-owned models that I won on eBay a couple of years ago. I've stripped them of their previous paint jobs and cleaned off any excess mold lines that were still remaining. I've also washed them and glued on a base of sand. The next step will be to spray paint them with an undercoat of black paint.
