Brass Knuckles - stainless steel from EDC Weapons. Review 

These brass knuckles are very strong, heavy, and meant for business. They are unique because they fold down into a ring so you can wear them (if you have large hands) or put them in your pocket or purse and, hopefully, get them through security at the airport. They are made from stainless steel, so they won't rust. They are distributed by Weihai Yimai E-commerce Co.,Ltd
