The Mooncup is a reusable menstrual cup around two inches long
and made from soft silicone rubber. It is worn internally like a
tampon but collects menstrual fluid rather than absorbing. Unlike
tampons the Mooncup is not a disposable product, so you only
need to buy one which should last you 5 years.

The Mooncup will hold 30ml of fluid, which is roughly one third of
the average total produced each period. A light seal is formed
with your vaginal walls allowing your menstrual fluid to pass into
the Mooncup without leakage or odour. You will probably find that
you need to empty your Mooncup less frequently than you
currently replace towels or tampons.

Available in two sizes:
Size A for women over 30 and/or have given birth vaginally
Size B for women under 30 who have not given birth vaginally
