This set of 4 ramps and stairs can help you create amazing sci-fi or industrial scenes! The set includes one double ramp with a walkway in between, one taller ramp, and two sets of stairs. They are made of plastic with high resolution graphics printed directly on the surface. They come unassembled and require super glue and about 10 minutes of your time to put together. I have used these in some of my own Minimate photos, and they look great in pictures or on your shelf.
