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.
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.

A re-usable alternative to a tampon. Small rubber cup that you stick up your floo to catch the jammy waste.
"Look mum, I've bought this new Mooncup and look how much womb it can hold"


"Do excuse me officer, I must go empty my Mooncup"

Not to be confused with buttercup. If you hold a Mooncup under your chin and it glows red it does not mean you like jam!!!

Disaster! Shit, I've flushed my Mooncup away!

Something you put 'up there' to catch all the 'stuff'. It's like a plastic tampon, but you can't squeeze it out to flavour your food.
