Full range of Vallejo Diorama Effects Please select your product from the dropdown list. Combined shipping will be charged automatically (you will pay the same amount for shipping no matter how many products you buy*). Once you have selected your product, you will see a series of images with the product description. The placement of our model in a diorama or vignette gives it a reality, a background and a history, an added dimension and a reason for the humidity, the traces of mud, of the dry sand of the desert or the dark earth of the wooded landscapes of central Europe.
