What is a model kit?

Term loosely applied to amateur
or semiprofessional model kits,
usually created in someone's spare time.
Most model kits are cast resin.
Model kits can vary widely in quality,
but many are superior works,
equal in quality, artistry and workmanship
to those produced by professional kit
companies.
Some model kit sculptors are
commissioned by pro kit companies
to create designs.
Model kits are frequently
limited to a certain number of copies,
which adds to their appeal to collectors.
