It's listed as Bones but it's actually a shiny hard thin gray plastic. It's also only about 2"x2"x2" which makes it look fairly shrimpy on the battlefield. Comes in three pieces, easy to assemble or take apart, but doesn't snap together, so if you raise the dumpster lid above 90-degrees then the whole assembly just falls off. Not a great value, but if you absolutely require a small plastic dumpster, then I guess it will work in a pinch.
