The skulls are completely produced by a 3D printer. Each comes printed in one peace only. You don't need to build the model. The kit comes unpainted, so model paints and other basic modelling tools are additionally required.
#Please note that a 3D printed model can show some kind of "steps" on the model. This is a result of the thousands layers used during the printing process. The steps are micro millimetre thickness and can be removed very simple. After you have cleaned your model, take a small flat brush and wet it with acetone! Than stroke the brush with fast up and down movements on the area where you see the steps on the model. You will see, that the visible steps disappear instantly - if necessary repeat this process until you are satisfied with the result! Please note security advice while working with acetone! Don't smoke, no flames, wear breath protection and gloves.
