These hand made solid brass knuckles have a wicked spike centered on each one. This is a set of 2 knuckles. Check local laws before ordering this set. We will NOT ship to California, Illinois, Michigan or Vermont because of laws in those states restricting citizens rights to effective self defense tools. As for size, this set fits my hands well and I have normal sized hands, would fit small to above average sized hands, if you have really giant monster sausage fingers and people often mistake your hand for an escaoed zoo creature then they might not fit. Will trade for 5 ounces of silver.
