These grill covers are OEM and originally came with Kenwood Road Series Peak Power 300W KFC-1666R radios. They are brand new, never used. Still in factory bag, but not sealed. They measure 6.5" diameter. I have (2) sets available. Purchasing a quantity of (1) will get you one SET of TWO speaker grills. If you desire (2) sets, please select a quantity of 2. They come from our non-smoking, pet-free home. 

Check my feedback for evidence I package items carefully and ship promptly.
