These paperweights are solid and very impactful, if you get my drift. We sell them in two sizes, Medium and Large. The medium holes have an inner diameter of 0.8 inches and the large have an inner diameter of 1 inch. Designed using solid steel instead of typical brass you’d find in a similar knuckles device. Like dusters. The best way I can describe the sizing is mediums are for normal hand people and larges are for big hand people. The larges are also a lot wider.
Knuckles are not legal in all states and cities. Customers take all responsibility for knowledge of their local laws.
