These are high quality ferrules with no manufacturing "lumps", like you would find on a lower quality ferrule. This is a pack of ten black iron ferrules.
This also eliminates the need of "turning" or sanding the ferrule. These are the highest quality ferrules money can buy. Pre-coned for an epoxy "cushion" to prevent shaft breakage.
