Kolderstok strives to offer high-quality wooden construction boxes for ships, unique in their kind. Models of famous ships from the Dutch Golden Age, ships from the VOC era, but also ships made famous by the wars in which they operated. Ships of famous names such as Michiel de Ruyter, Marten Harpenszoon Tromp, Jan and Cornelis Evertsen (aka Keesje de Duivel) and Adriaen Banckert.

For the design of the Kolderstok ships, old images and existing ship models were used as much as possible, in order to come to the most historically accurate model possible.

Most Kolderstok models are intended for model builders who have made a wooden model before. The difficulty of the models ranges from 1 star (starting builder) to 4 stars (very experienced builder).
