This Kendra Scott Letter Gold Disc Reversible Pendant Necklace is super easy to wear. Just open the lobster clasp and put it around your neck. Adjust the single adjustable sliding bead to get the perfect fit. You can wear the pendant one way for a certain look and flip it over for a different style. It's great for layering with other necklaces too. As for care, keep it away from harsh chemicals like perfume and hairspray. When not wearing it, store it in a jewelry box to prevent scratches. Since the iridescent abalone is unique, don't be surprised if the exact colors and patterns are a bit different from the picture you saw online.
