Not only are these pyramids 2" tall, each side of the base is also 2" long. There are 3/4" holes in each face of the pyramid that dowels can be run through to create a longer base... if the paint job needs it. Additionally, there are tapered screw holes in the feet of the pyramids in case you need to make sure they stay secured to the place that you put them. And when you are done, they stack very nicely in an attractive tower :-)
