These products were developed based on the long-popular Chinese puzzle (tangram), which can not invite non-linear thinking, such as arc-shaped and quatrefoil.
The products are a set of quatrefoil puzzles with 12 quatrefoils in three different partition patterns, and each quatrefoil has seven pieces.
These products can be called "Constructive Quatrefoil Tangrams," which invite unlimited geometric design possibilities. Anyone can still find other different pattern of the quatrefoil tangram.
The patterns of quatrefoil tangram also can be used in daily life such as jelly-glue collage, jigsaw tables and so on.
