In fact the model is small (5cm x 5cm) but very well designed and excelente quality. Tool are recommended: two tweezers (a flat head for bending a thin head to head parts and twists), a cutter to separate pieces of aluminum foil and if you have a magnifying glass on walk it can be useful. It will take a good view and arm yourself with patience (refrain nervous) but the result is really beautiful on a small pedestal in a showcase.
