Creature is proud to offer a very limited amount of Skeleton Key MFG Master Grinders. We included (or Navarrette included) a Creature sticker in every package. Navs had this to say: "Grinders. Copers. Call them what you will, they are part of skateboarding past. A part that made skateboarding what is is today. Some say "grind like a man." We say, lay sod like a man, we are skateboarding." So, chances are...you'll miss out. But, give it a shot there champ. Copers attach to your truck hangers to make grinds even faster! Like rails for your trucks! '80s throwback style!
