These are wicked looking knuckles and are sold for novelty purposes only. They make a great paper weight or desk item (to inspire fear) for the office and are sure to leave a lasting impression (oh yeah, the wit flows like wine around here). Gray textured finish. These are super heavy duty weighing in at an impressive 6.4 ounces. Fits up to ring size 13. These are not legal to purchase in some locations so be sure to check your local laws.
