Brass Knuckles

This is a pair of brass knuckles, made of plastic. They are meant to fit people with fingers of 20 mm or smaller, so if your hand is bigger you may have to scale up the model. Please, DO NOT hurt or attempt to injure anyone with this. This is meant to be a self defense item, or a demonstrational item.
If you like the design, and you would like to help me create further work, please check out my GoFundMe! https://gofund.me/5c559dd9
