We just received a new shipment of burl cork rings from Portugal and included was a new Stacked Burl Ring called Cookie Crumble. These new rings will add a wonderful highlight to your custom grips. They are made from 5 different layers of burl cork. We will be using them in our custom burl with accents grips. The rings are 1-1/4″D by 1/2″long with a 1/4″ hole. They cut and sand very easily and will compliment both standard brown burl rings or regular species cork rings.
