To kids, the Cherish Ball is seen mostly as a special Ball for Pokémon given as gifts or rewards. For adults, however, the Cherish Ball (or at least its iconography) takes on a secondary use, to symbolize a strong love between people, platonic or otherwise. Some will even take Cherish Ball shells and refit them to hold things such as engagement rings.
