4x4x4 Double-Ended Hybrid Resin Casting Sphere Mold: 
This mold features Double removable end caps.  This mold allows both end caps to be removed without the use of tools to help facilitate removal of casting.
 
This Gen3 mold incorporats a reusable/replacable gasket sytem made from a very tough polymer.  This system eliminates most leaks or seeps at the cap, which can be a problem on tall or larger-volume molds.
 
Our hybrid sphere molds cast a cube-shaped blank that can be turned on a lathe into a sphere.  They do not produce a round or sphere-shaped object.
