This 87th HO scale trailer is the type used to haul radioactive or poisonous industrial materials or waste to chemical or nuclear facilities. This piece is offered in the Frosted Ultra Detail Material only. I also have the containers that fit on the back, but due to the size and that they are usually made of concrete, I've made these available separately so they can be printed in the least expensive material. Should there be a problem, contact me via the shapeways link, or direct via Email to modelmechanic@gmail.com
