Wargaming models are often sold in parts. In the case of plastic models, they're often sold still affixed to their sprues. The player is expected to cut out the parts and glue them together. This is the norm because, depending on the design of the model, it may not be possible to mold it whole, and selling the parts un-assembled saves on labor costs. After assembling the model, the player should then paint it to make it more presentable and easier to identify on the game table. Understandably, the time and skill involved in assembling and painting models deters many people from miniature wargaming. Some firms have tried to address this by selling pre-assembled and pre-painted models, but these are rare because, with current technologies, it is hard to mass-produce ready-to-play miniatures that are both cheap and match the beauty of hand-painted models. The other options for players are to buy finished models second-hand or hire a professional painter.
