These rust-proof eyelets are made of silver-colored brass and have an inner diameter of 14 mm. They are an easy way to add embellishment to your favorite clothing or home décor. These eyelets should be applied tightly so that they do not turn- this prevents the eyelet from tearing out. Prym offers eyelets with washers for use with the VARIO Creative Tool (390903) and the matching tool set (673127).
