Thank you for viewing. [Product Description] Size: (Length) 15mm ✖️ (Width) 8mm Color: Antique Gold / Red Body Material: Brass Crimp Legs: Brass (4.5mm) Washers: Iron Quantity: 5 pieces [How to Attach] Make a hole of about 2mm in the leather, pass the crimp legs through the hole, and make sure the crimp legs protrude at least 2mm from the back of the leather. Place thick paper or a scrap of leather on the anvil to prevent scratches on the surface of the body. Insert the washer from the back and attach it by hammering. It's the same as attaching decorative crimps, so even beginners can easily attach them. [Notes] Since the crimp legs are crushed to attach, please note that it cannot be easily removed like a screw type once attached.
