20 Pellet Swaging dies for PCP

Posted this here because I know some of you make your own pellets- 

Matt Dubber has on his most recent YouTube video in Patagonia a segment where they press their own pellets. Does anyone know where to get that press? It sounds like he said they got it from HN Hen out of China. It’s a 20 pellet die for swaging pellets out of lead wire. Looks super cool. Searched online but all I could come up with was one from Corbin and a few others - none appear to be JSB like. The ones in the video looked just like JSB domes exact.
