Small platform. Deploy it between two building's rooftops, to connect them. Sideboards on a platform can hide base of a miniature (that is helpful in Infinity wargame, there model in "prone" state has considered height of its base).
Platform connects to a building by special connectors for better usability.
We recommend you to paint it with acrylic paints. In addition, you will need PVA glue to assemble it.
The product is sold unassembled and unpainted.
