These tips are 18k gold plated and stunning! I personally think these would look best with white or cream bolo cords. These arrowheads are one of a kind, and I only have this one pair, so don't wait on these guys! These bolo tips will accomodate 3, 4, and 5mm bolo cords, all of which I have. No need to worry about whether or not they will fit the cord color you select! When putting in your bolo specifications, please select either one of the standard tip options. If I see any bolo tip add on like this in your order, I will assume that you would like the tips you have added, rather than the standard tips. Please do not hesitate to reach out to me if you have any questions.
