Listing includes one pair of cufflinks. Cufflinks are sterling silver plated and measure 20mm in diameter ( An inch is approx 25mm) water proof but not water resistant. Please leave initials in FIRST….MIDDLE….LAST order I have a special process that I use to ensure your cufflinks look as clear as they do in the listing photo. The images for the cufflinks are printed on very high quality paper and are placed under a nice thick glass which also enhances the image and then placed securely into the shiny silver plated tray. Your cufflinks will be carefully packaged to ensure their safe arrival and will also be ready for gift giving! Your wedding day is a special day and I will make sure that your cufflinks are just as special!!
