Review on ZRM Copper Keepers Locking Wrenches by Karla Richter

My wife volunteers regularly and is rewarded with uniquely designed hat pins or lapel pins. These items sat in a plastic container in a closet and were stacked for many years. We came across your product while randomly looking for an item that can reliably prevent these unique pens from falling. We took a chance with your product and it paid off. Now she shows these unique badges on her backpack. We check them weekly in case the socket head cap screw might be loose. As long as they stay tight and we have confidence in the product.
