Dynasphere DYVA Vanadium Billiard Ball Set – Phenolic Resin

Dynasphere’s Vanadium set, model DYVA, gives pool players a phenolic resin ball set with published tolerances rather than a general promise of quality. It is sold as a full set, so there is nothing to configure before checkout.

The box lists a 57.2 mm size, a weight of 169 g (plus or minus 1.0 g), a density of 1.73, roundness of 0.03 mm or better and hardness of at least 59 Rockwell. Inside are one cue ball marked with two black triangles, seven striped balls, eight solid balls and a cleaning cloth. The set suits regular players and rooms that want balls with measurable specifications, and the cloth helps keep the finish clean between sessions.
