Prym Brand These stainless hooks and eyelets, made of black-coated brass, are excellent for any piece of clothing where fastenings need to be installed discretely and invisibly. The hooks and eyes can be sewn very easily into trousers, jackets, skirts, blouses, or lingerie thanks to their laterally-curved eyelets. They can also be used e.g. as additional support for zip fasteners in skirts or dresses. These coated fastenings’ flawless and high-quality workmanship make it absolutely comfortable to wear, even with direct skin contact.
