Featuring Cell Technology, the Cell BK ON® Cyborg break tips are a sight to see – literally! Cyborg’s Cell Technology results in a tip that is hard in density but has a bit of elasticity to it therefore your break shots are a lot more controlled and the tip is able to retain chalk for optimal breaking performance. The other cool part we can’t get enough of is that the Cell BK tips actually absorb the surrounding light and will glow in the dark. How cool is it to have an actual glow-in-the-dark break tip?! As an added bonus, these ON® Cyborg Cell BK break tips give you the ability to make those tricky jump shots as well and you can choose from blue, orange, pink, white or yellow color of tip.
