They don'tlook  like plastic or card to me, they look laser cut mdf, or something similar.

The visible fixing tabs might be a problem, and may need filling and sanding after assembly. Glue will likely be simple PVA (white wood glue), and painting can probably be done with basic interior wall paints, or acrylics.
