Modular polo mallet head design

the caps are not 'in' the pipe, they are bonded to the pipe - see his description

They're fused? I think on a molecular level it's one piece of plastic...

The magic here is that the two are fused together. They are, molecularly, the same piece of plastic. It's the same technology and equipment as the gas company uses. My hope is that if it can stand up to gas or liquid at pressure, it can hold up to polo. We'll see. A few prototype models will be sent out to test markets while I work out the kinks in the manufacturing process and use their feedback to make improvements
