Dinnissen Modelbouw is a specialist webshop for military scale models, decals and related modelling supplies, with a particular focus on products for model railways. Its main ranges cover scales 1:87 and 1:160, alongside selected products in 1:72 and 1:76, as well as offerings in other scales. The catalogue includes plastic and resin construction kits, finished and unpainted models, vehicles, figures and accessories, plus decals for a variety of subjects and scales.

The shop also produces its own decals and can customise items such as vehicle number plates on request. Customers may commission insignia and other markings as decals; a small design fee may apply when a requested design cannot be added to the regular range. Dinnissen Modelbouw offers paints for Royal Netherlands Army vehicles, including colours and mixing guidance for recreating the earlier RAL 6014 olive-yellow finish, as well as paint suitable for tyres. Its services include a gallery of completed models in 1:87 and 1:160, where customers can view examples and submit photos.
