I got the size 2, and only had worn another menstrual cup before this one (meluna classic large), so I am experienced, but not extremely. The reason why I got this is because I needed a cup that would hold more volume but would be short enough for me, minus stem (low cervix-er). I have only worn this once, but I already love it. I was worried it would be too soft, but it has actually almost the same softness as the meluna classic, and it opens A-ok, I barely had any issues. I love the colors, it's like a rainbow exploded in the cup! There's a volume scale built-in, which I think is great for people who like to keep a volume log. I wish it had more unit lines so I could have a better idea of how much is filled, but alas, a scale of any sort beats no scale at all. The stem was a little too long for me, so I cut off almost all of it, taking care not to puncture the cup itself. I wish this cup was offered without a stem as well. Overall, great purchase!
  • Beautiful colors
  • Stem can be cut for a more comfortable fit
  • The material is soft to the touch, but the cup itself is not too soft to bend and open (almost equivalent to the meluna classic)
  • It has a scale
  • Comes with a disinfecting recipient and instructions
  • Stem is too long for me (can be cut)
  • Scale not specific enough
This is my first cup, and I found it incredibly easy to use. I did not have any leaks at all. The soft stem was really comfortable.
  • Easy to use
  • good size
  • firm enough for a beginner
  • soft enough for minimal discomfort
Good purchase
  • Liked the color
  • Alles gut
Pretty and practical.
  • Big capacity. Very smooth so easier to rinse and keep clean than my old Mooncup. Bigger suction release holes don't get clogged. Nice colours.
  • Expensive.
Which sizes are available and which of them should I order?

Yuuki offers two sizes. One for women who have already given birth and one for women under 28 years of age who have not yet given birth. The Yuuki cups come in two sizes: No. 1 - small and No. 2 - big. The difference between the small and big cups is one of the biggest differences among those offered by cup manufacturers.

You can find the sizes on our blog .

What is the useful life of the cup?

Most manufacturers state ten years. Theoretically, it can last till the end of one’s life because it is made of the same type of silicone as that implanted during surgery. It is up to you whether to purchase a new cup. We provide a two-year warranty on the Yuuki cup.

How often do I have to empty the cup?

It depends on your period. The intensity of every woman’s menstrual flow varies. If your menstruation is average to heavy, you should empty the cup every 3 to 10 hours. Some women with very low menstruation may even go 12 hours before emptying the cup.

On heavier menstruation days, you may have to empty your cup more often. If you have tried already the big cup and have seen that you have to empty it every three hours, you have an extremely heavy period. That need not be a problem but you should discuss it with your doctor. There are means of controlling such heavy menstruation.


With a little patience, inserting the cup is comfortable and quick, even during the first few times. We’ve prepared a few tips for you to make it easier to start using the cup.
