Nubian Fold-up Cardboard Pyramid

The Nubian Fold-up Cardboard Pyramid is made from heavy-duty 275 lb test cardboard, precision cut to a 72-degree slope angle, similar to the pyramids in ancient Nubia. This pyramid is held together with super-strong Gaffer's tape, a high-quality duct tape made out of cloth. it is designed to be firm and steady when placed on a flat surface, but folds up easily and quickly when not in use. Use it for all sorts of experiments from energizing water to sharpening razor blades. Most of the well-known pyramidologists, including Patrick Flanagan, Max Toth, Antoine Bovis, and Karel Drbal all started with cardboard pyramids and achieved impressive results. And if you can get over the goof-factor, meditating with one on your head can be an amazing experience! • Exclusively handcrafted in the USA by Precision Pyramids. • Ships via USPS 1st Class Mail usually within 2-3 days. • This pyramid is approximately 10 inches (25 cm) wide at the base and 14.5 inches (37 cm) high.
