What is an MDF square base?

The advantage of using this material is its durability and stability since they are rigid and less prone to warping or bending compared to other materials like plastic or resin. They provide a solid foundation for miniature models, ensuring they stand securely on the tabletop without wobbling or toppling over.

These types can be customized and decorated according to the player's preference.

Some players also choose to add flocking, long grass flock, or other terrain materials to enhance the visual appeal of the base.
