"The Mooncup is available in two models.
Model A measures 46mm in diameter and 50mm in length.
Model B measures 43 mm in diameter and 50mm in length.
Both models have a pull stem 21mm long, which you can trim to the length that is right for you.
Model A is recommended for women who have given birth vaginally or who have had a caesarean section and aged 30 or above.
Model B is recommended for women who have not given birth or who have had a caesarean section and aged below 30."
