Simon Carter cufflinks USED Simple look with black onyx (I believe it's not real onyx) and zirconia, making them easy to use. I'm selling these because I have too many cufflinks and am decluttering. There are no noticeable scratches or stains, but please understand that these are USED items before purchasing. * As shown in the photos, the outer box is dirty and not in good condition. Shipping is only available on weekdays.
