How to Use:

If you can put in a tampon, you should find it relatively easy to insert a menstrual cup. Just follow these steps to use a cup:

  • Wash your hands thoroughly.
  • Apply water or a water-based lube to the rim of the cup.
  • Tightly fold the menstrual cup in half, holding it in one hand with the rim facing up.
  • Insert the cup, rim up, into your vagina like you would a tampon without an applicator. It should sit a few inches below your cervix.
  • Once the cup is in your vagina, rotate it. It will spring open to create an airtight seal that stops leaks.

You shouldn’t feel your menstrual cup if you’ve inserted the cup correctly. You should also be able to move, jump, sit, stand, and do other everyday activities without your cup falling out. If you’re having trouble putting in your cup, speak with your doctor.


How to take your menstrual cup out

To take out a menstrual cup, just follow these steps:

Wash your hands thoroughly.

Place your index finger and thumb into your vagina. Pull the stem of the cup gently until you can reach the base.

Pinch the base to release the seal and pull down to remove the cup.

Once it’s out, empty the cup into the sink or toilet.




  • They’re budget friendly. You pay a one-time price for a reusable menstrual cup, unlike tampons or pads, which have to be continually bought and can cost upward of $100 a year.
  • Menstrual cups are safer. Because menstrual cups collect rather than absorb blood, you’re not at risk of getting toxic shock syndrome (TSS), a rare bacterial infection associated with tampon use.
  • Menstrual cups hold more blood. A menstrual cup can hold about one to two ounces of menstrual flow. Tampons, on the other hand, can only hold up to a third of an ounce.
  • They’re eco-friendly. Reusable menstrual cups can last a long time, which means you’re not contributing more waste to the environment.
  • You can have sex. Most reusable cups need to be taken out before you have sex, but the soft disposable ones can stay in while you get intimate. Not only will your partner not feel the cup, you also won’t have to worry about leaks.
  • You can wear a cup with an IUD. Some companies claim a menstrual cup could dislodge an IUD, but a 2012 studyTrusted Source debunked that belief. If you’re concerned, though, check with your doctor about using a menstrual cup.


Environmental Impact:


Unlike disposable period products, the Moozii Cups are reusable for years and it has a minimal impact on the environment compared to tampons and pads.

The lifespan of the cup means potentially saving the environment for the packaging and material waste of more than 2400 pads or tampons per user. To put that into context, one Moozii cup will save the environment for one truckload of waste in 10 years for every single person who switches to a cup.

That’s quite an environmentally friendly solution compared to the conventional alternatives that exist on the market today.
