"To put these earrings on, gently twist them open, insert into your ear, then snap them closed by crossing the two pointy ends the OPPOSITE way they were originally. The tension created from bending them open will then hold them closed. Make sense? If not, as soon as you get them it'll be clear and they'll immediately be your new everyday hoop earrings."
Regular earrings are about an inch wide, mini are just under half inch.
