The streets are grimy, that's a fact. Ditches are even worse. No matter what grip you run once it gets clogged up with dust, dirt, and asphalt grime you lose traction. The Flick Brick removes all the grime from your grip and makes it like new. No one likes to re-grip an old board. The idea is to set it up right and go to battle. The Flick Brick is small enough to keep in your backpack, measuring at 5" x 1.5", and good to go. "Clean That Grip, Keep That Flick!"
