This red 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 6 cm long and the split ring is 8 mm in diameter. I will attach any sterling silver charm in my store onto the lanyard when you purchase them at the same time. Look also for the purple, pink, light blue, and black lanyards also in my store for the same price!!
