ITSPHUN stands for Interconnecting Triangles, Squares, Pentagons and Hexagons Using Notches. I purchased a basic set of these shapes quite recently at a very affordable price. The kit is easy to use and comes with an information pamphlet.
Special orders such as different shapes, colours, designs and materials are available on request. Great for experimentalists like myself!
