This 3D sterling silver charm is a skate key! It is 23 mm tall and 7 mm wide.

I also have volleyball, soccer, tennis, baseball, dance, cheer leading, swimming, ballet, tap, skating, skiing, water polo, wrestling, football, karate, hockey, lacrosse, golf, running, bowling, skating boarding and others I can't think of right now.
