Used to treat the ends of nylon coated wire. A wire diameter of 0.3 to 0.4 mm is recommended. As shown in the image, you can use a flat wire to push the pin in and fix the wire. *The pin is hard, so if you pinch it at the base of the flat head, it will be easier to push in. *As this is an accessory, the color may be changed to reflect changes in fashion. Also, during the processing process, color shading may occur without prior notice. Please note. (Some parts may differ in color from other parts.)
