This small dolphin charm is perfect for a child’s charm bracelet but not too small that it won’t work for an adults bracelet. Two of these charms make cute earrings. This charm is about 1/2" x 7/8" and weighs about 1.8 grams. It is one sided (concave on the other side). It comes with a 6mm split ring already attached making it easy to put on a charm bracelet or necklace.
