PacBay's Graphite Colored Foam Arbors are made of polyeurethane. They're lighter than cork, but much harder. They give rods maximum sensitivity by transmitting strike signals and lure actions from the blanks through the reel seats and straight into anglers' hands. The porous surface of these arbors enhances glue bonding.
