The RAD Block does it all. (1) It elevates your game by raising the height of your RAD Roller and RAD Rounds for better leverage in hard-to-reach places. (2) It stabilizes your tools so you can isolate pressure with no rolling. And (3) it has handy storage slots for easy, full-kit travel. And now you can get all three tools at a mighty fine discount when you buy them all at once. Lucky you. Kit includes RAD Block, RAD Roller and RAD Rounds.
