Real world
This container is worldwide used to transport various goods. One can see those containers (and others in different sizes) loaded on trains, ships and truck trailers. These containers are made according to the international standars, so they fit every vehicle anywhere in the world. In Europe, they can offten be seen loaded on Sgnss wagons in train coherent sets. You can order a Sgnss wagon right here.
Model
The model is made according to the NEM 380 model standard - it has four pins on the bottom and four pinholes on the top, so you can easily stack them on top of each other. The container also fits this Sgnss wagon and most commercially produced wagons, intended to carry containers, as well!
You will receive two separate parts - the container itself and its bottom. This is due to the technological requirements and it also allows you to add an extra weight by inserting a piece of metal inside (do not forget to fix it with glue - definitely use super glue). Put both parts together (there is only one way you can do it, so you cannot do anything wrong) and glue them, then just paint it and you are ready to go. Color entirely depends on the choice of your own, since real-world companies also use different color and even color patterns. There is no standard for this.
