These are limited edition Glow-in-the-Dark attachments.

3D Printed inner core.

6mm threads fit these poles: InZone XXL, InZone Mini, and InZone Saber, and SOME of the InZone XL's.

This ball comes with a 2.5" long M6 threaded screw and nut.  If you want to put this on a pole with a different thread, you'll just need to remove this screw and nut and replace it with the correct size.  Max Disctance metal poles take M5 threads and the CF poles take 8-32.
