This butterfly CTR ring is a cute and colorful choice for Primary children. It features a butterfly alongside the CTR reminder, and an open back lets it fit any size finger. Made of soft, flexible silicone, it adjusts to fit little fingers of almost any size and won't turn skin green like metal rings can. At this price, it's easy to buy one for every child in a Primary class, for a family home evening lesson on choosing the right, or as a reward for memorizing an Article of Faith.
