The Volume is my current favorite Delrin. The inspiration for its shape came from crossing an Omnicron with a Capella, and it shares its shape with the Accent. It's the same diameter as the Cosmo at 53.30 mm, so it really darts between strings easily. And at a much wider 43.10 mm width, string hits have never been easier. If you like my previous work, you'll definitely appreciate this!
As with all my yoyos, it can be completely customized in color, finish, and bearing size. Check out the options link for details.
