• Mooncup Menstrual Cup

    The Mooncup is a reusable menstrual cup, around two inches long and made from soft medical grade silicone.

    It is worn internally a lot lower than a tampon but, while tampons and pads absorb menstrual fluid, the Mooncup collects it.

What is a Mooncup?

Benefits of Mooncup

Whether you want to reduce your carbon footprint, save money or just look after your health, there are many reasons to choose the Mooncup.


The reusable Mooncup offers a simple way to dramatically reduce the amount of waste you produce.

  • One woman will use over 11,000 disposable sanitary products in a lifetime
  • 22 tampons or towels are used, on average, each period
  • In the UK alone, 4.3 billion disposable sanitary products are used every year

These items, their packaging, applicators and backing-strips will end up in landfill or in the sea.


The Mooncup is made from soft medical grade silicone and is latex-free, hypoallergenic and contains no dyes, BPA, phthalates, plastic, bleaches or toxins. 

Because the Mooncup is non-absorbent, it will not cause dryness and does not disrupt your body’s natural pH levels (35% of the fluid tampons absorb is natural moisture!). 

The Mooncup has measurement markings, enabling women to accurately report menstrual blood loss to a doctor or gynaecologist. 

The Mooncup does not contain any absorbency gels, additives or perfumes. Unlike some conventional cotton sanitary products, it is also free from pesticides and GM materials. 

Tampons can cause dryness and leave fibres behind. The Mooncup is designed to respect your natural balance.


The Mooncup holds at least three times as much fluid as the most super-absorbent tampon, giving longer lasting protection on heavier days. And, because it is non-absorbent, it won’t cause dryness when your period is light.

Because there is no string, the Mooncup is completely discreet – and you only need one so there’s no need to carry bulky spares or worry about disposal of used products or packaging.


One Mooncup lasts for years, and costs the same as the average woman will spend on disposable sanitary protection in three months.


Mooncup Instructions

Each Mooncup comes with a comprehensive Usage Guide

Below you’ll find some general information on Mooncup use. Each Mooncup comes with a comprehensive Usage Guide with full instructions on use and care of your Mooncup. Mooncup Ltd also has an Advice Centre for any queries because, like anything new, using the Mooncup correctly can take a little practice. 



We recommend you empty your Mooncup every 4-8 hours. As with tampons, it’s important to have clean hands when removing and inserting the Mooncup. Then simply rinse your Mooncup and reinsert.


Which size Mooncup should I use?

The Mooncup and MCUK are available in two sizes:‘A’ and ‘B’. Size A measures 46mm in diameter and 50mm in length. Size B measures 43 mm in diameter and 50mm in length. Both sizes have a pull stem 21mm long, which you can trim to the length that is right for you.

Sizing is based on pelvic floor tone, not menstrual flow, and it’s important to get the sizing right to get the best from your Mooncup or MCUK. Pelvic floor tone will vary according to your age, childbearing history and what sort of exercise you do. Corrective surgery to the vagina will also have implications. Check the guidelines to see which size you need:

Size Table

Size Size A

Because vaginal and pelvic floor tones naturally reduce with age, the size ‘A’ is recommended for women aged 30 or over. The difference between the ‘A’ and the ‘B’ is only small (3mm), but it is crucial!

Size ‘A’ is also recommended for all women who have given birth vaginally, regardless of age.

Size Size A

Designed for young girls and women under the age of 30 who have not given birth vaginally. It may also be suitable for women over the age of 30 who have had corrective surgery to the vagina, or who are advanced in tone-maintaining activities such as yoga, dance or pilates.
