Foamboard 3D puzzles

Foam board

— sheet material in the form of a layer of foamed polymer (for example, polyurethane), glued on both sides with thin cardboard. Due to this foam board combines low weight and good rigidity. Another feature is that the details of such puzzles can be made in the form of flat sheets, which, when assembled, are bent in specially provided places and folded into three-dimensional structures. Thanks to this, quite large and voluminous items can be assembled from kits that, when unassembled, take up a minimum of space. In general, this material is considered perfect for puzzles that replicate buildings; most of the sets dedicated to architectural monuments are made of foam board (although there are puzzles on other topics).
