The parts come on two sprues moulded in a hard grey plastic. Parts are easily clipped from the sprues though (as ever) it is hard to do so without leaving tell-tale marks on the track surfaces.
The Sturmtiger was given desert yellow flecks to the green and brown areas to create an "Ambush" finish and then both models were weathered with Vallejo Sepia wash and high-lighted with Vallejo Iraqi Sand. They were both based on sand covered mdf bases (as all my AFVs are) and markings added from my ever diminishing supply of surplus Dragon decals.
Excellent little models, fairly straight forward to assemble and enough detail to lead to a good finish. These are such good value at approximately £3 you cannot go wrong. What's not to like...?
