These THIRTY light blue thin cord cell phone lanyard will hold any charm on it's silver (not sterling silver) split ring. The cord is almost 1 mm thick. The entire lanyard is 60 mm long and the split ring is 8 mm in diameter. The photo shows one, but you are buying two. I will attach any sterling silver charm in my ebay store onto the lanyard when you purchase them at the same time. Look also for the purple, red and black lanyards also in my ebay store!!
