COBI is a Polish construction-block manufacturer founded in 1987, known for detailed brick-built models for both younger builders and collectors. Its range focuses strongly on military history and transportation, with scale models of tanks, aircraft, ships, cars and trains alongside architecture and licensed collections.

COBI develops and manufactures its blocks at its own production facility in Mielec, Poland, where the process runs from product design and mould-making through to production. The company specialises in detailed models with printed elements and realistic proportions, using European-origin materials.
