This Gold Color Bolo Tip will fit almost any cord size from 2mm to 6mm, and the ringed design will look great with any bolo design! Just add a drop of glue in each tip and insert the ends of your bolo cord. Our favorite glue is E6000. A bolo tie (sometimes bola tie or shoestring necktie) is a type of necktie consisting of a piece of cord or braided leather with decorative metal tips – secured with a clasp or slide.
