It’s a hybrid between the copper bopper billets and the Solid Copper Billets. More expensive due to machining costs of the handles and expensive copper. It boasts strong durability, accuracy, forgiveness to error and will out last any lead filled Copper Bopper Billet saving you money in the long run. These tools do not contain lead.
