Three Pyramids Mold Set, Nubian 72°, Russian 76° & Golden Hexagonal, 20% OFF, Golden Ratio Geometry, Self Lubricating Polyethylene

The physical proportions of the Nubian pyramids differ markedly from the Egyptian edifices: they are built of stepped courses of horizontally positioned stone blocks and range approximately 6–30 meters (20–98 ft) in height, but rise from fairly small foundation footprints, resulting in tall, narrow structures inclined at approximately 70°.
The golden hexagonal pyramid has a regular hexagon in the base, six triangle sides, and it contains the golden ratio.
