Product Description

Made in Germany from 100% medical grade silicone, the Merula Cup is an excellent option for women with any cervix height and any degree of pelvic floor strength (or lack of). As a one size fits most and one of the highest capacity cups on the market, the Merula can hold up to 38ml of menstrual fluid. This is around 10-15ml more than most other cup sizes. Not only will this higher capacity mean less bathroom trips throughout your day, the vibrant colours and the co-ordinating cotton pouch will just make your day feel that little bit brighter.

The Merula is designed in such a way that it does not need to be completely open after insertion. As long as the edge has opened, the cup itself can be worn in a folded state, while still providing leak free protection. The exterior of the Merula is smooth, with no protruding top rim. This makes it more comfortable for women who experience discomfort from other ‘rimmed’ cups. The unique 3 rung ladder stem can be easily trimmed and allows for easier cup removal, and the more spherical shape of the Merula means it is more suited to varying cervix heights. Finally, the lesser vacuum level of the Merula makes this cup suitable for any pelvic floor condition, whether weak or very strong.

If you have a very heavy flow, you may find the 50ml capacity of the Merula XL more suitable.

Using the Merula Cup:

The Merula menstrual cups work differently to traditional bell shaped cups, and therefore, may require a few cycles to adapt too (particularly if you have used traditional shaped cups previously). While most bell and v-shaped cups are designed to sit below the cervix, the Merula is designed to have the cervix sitting within it. We recommend watching the following video to learn how to correctly insert and remove the Merula. We have also listed a few other helpful tips to get you started.



Positioning the Merula Menstrual Cup


  1. Before inserting the cup, feel for your cervix. Fold the cup into the punch down fold to insert it. Once inserted, push the cup in the direction of the cervix and open it in front of the cervix/push the cup onto the cervix while opening the cup.
  2. To help the cup open, push into the folded side of the cup and gently press away the vaginal wall to create more space. Once the Merula Cup’s rim has expanded and created a slight suction on the vaginal wall (this is hardly noticeable), its body can be worn squished and does not have to expand fully.
  3. Sometimes using a water-based(!) lube can be helpful. Apply the water-based lube on the cup’s rim, additionally it can be helpful to also apply the water-based lube on your cervix. This helps the cup to slide onto the cervix easier.
  4. The Merula Cup must not be removed by solely pulling on the ladder stem. It is important that the seal is first released. If the cup is positioned high up within the vaginal canal, you can hold the stem and gently move the cup down using ‘zig-zag’ movements. Once you can reach the cup, break the seal by pressing against the cup body, and proceed to remove as normal.

IMPORTANT: Menstrual Cups have been associated with Toxic Shock Syndrome (TSS). TSS is a rare but serious disease that may cause death. Always read and keep the information contained with your cup. Use only as directed. Discontinue use of this product and consult a GP if you experience any adverse side effects.

    Gives me the worst cramps I’ve ever had.

    Great for a high cervix with the ladder. I’ve used three different cups previously and this one is definitely best fit for me.

    I’ve been using cups on and off for 10 years and tried this one as I have heavy flow for a couple of days at the start of my cycle.
    I’m pleased with the cup, but it is not as user friendly as other cups I have used.

    Pros – capacity + less noticable once placed (I have to place cups high which can cause irritation).
    Cons – more difficult to place (doesn’t open up consistently as silicone is more pliable and due to shape) + more difficult to remove.

    Would not recommend for first timer.

    I am not a first time cup user and I found this very awkward to insert and didn’t seal very well, led to a lot of leakages. Really uncomfortable and caused painful cramping. Also awkward to remove because you have to stick your fingers inside to slightly crush the cup to break the seal, as there are no vent holes around the edge. Would not recommend.

    This is my ‘goldilocks’ cup… and definitely will be yours too! Totally recommend to everyone!
    ((The first cup I tried was way too long; had to be emptied often; and leaked a lot… I wasn’t a happy chappy.)

    The Merula is very easy to use; easy to insert & remove; no leaks or nasty surprises during the day or at night; easy to clean; gorgeous little storage bag! Xx
