Key Benefits

With a Ruby Cup, your health and comfort come first.

When we say you’ll never want to manage your period with anything else ever again, we mean it.


It’s the ultimate period game-changer. Not just for you, but also for the young women who will receive a donated cup thanks to your purchase. 


When you buy a Ruby Cup, you aren’t just investing in a worry-free period for yourself, you’re also sharing the same benefit with someone in need.


 A Ruby Cup has 3 times the capacity of a super tampon. That means you can wear it for up to 12 hours, depending on the heaviness of your flow.


 You’ll use up to 12,000 disposable period products in your reproductive lifetime. Swapping to a Ruby Cup dramatically reduces the impact your period has on the environment.


Ruby Cups are made from 100% medical-grade, soft silicone and are blissfully free from plastics, latex, toxins and bleaches.


The cost of one Ruby Cup is equal to the cost of 5-6 months of traditional period products. Because your cup lasts up to 10 years, you’ll rake in long-term savings of more than 95%.


All Ruby Cup variants are registered with the Vegan Society

There’s a reason you never felt comfortable during your period

You’ve been using products that don’t have your health or comfort in mind. Our thoughtfully designed menstrual cups were made by women for people with periods.


Ruby Cup comes in two sizes in order to fit every body regardless of age, cervix position, the heaviness of flow or whether you've been intimate or given birth.

Meet the ultimate





"Don't wanna live without it anymore!"

Ruby Cup is perfect if:

You’re so over damp pads and annoying tampon strings


You’re frustrated by the monthly waste single-use period products produce

You're tired of the tampon tax and the cost of your period. 

You’re suffering from heavy periods and menstrual cramps

Julie Weigaard Kjaer,

CEO & Co-Founder

I didn’t just want to create a better menstrual health solution for myself,

I wanted to make it accessible for women and girls in low-income communities, too.

Ruby Cup was created out of a desire for change.

Julie was introduced to menstrual cups by co-founder Maxie at uni.


“Until then, I never thought that there might be other solutions out there. The menstrual cup was a life-changer for me! It suited my needs much better than tampons or pads ever could."

Convinced that cups are the best period product out there, she decided to do more than just spread the word about menstrual cups. Together with her two co-founders, she designed her own easy-to-use period cup.  


Julie didn't want the experience to stop with the person buying a Ruby Cup. She wanted every Ruby Cup to make a real difference, for those who can afford to buy one, and especially those who struggle to pay for period products. 

After experimenting with different business models, the three founders decided that the heart of Ruby Cup's business would be a Buy One Give One model. 

Since 2011, every single Ruby Cup sold includes another one that is donated to a young woman who struggles to get access to safe period products. 


How do I know which menstrual cup size to choose?

We do not recommend that you choose your menstrual cup based on whether you have already had sex, given birth or not, or your age. Since each body is anatomically unique, these are not very reliable factors. The two key factors to look out for when choosing the right size are:

  • Position of your cervix (don’t know how to measure it? Check this out.)
  • Heaviness of your menstrual flow
Have a look at this chart to see which Ruby Cup size is the right one for you:

How does a menstrual cup work?

1)Fold the Ruby Cup using a fold that works best for you. 2)Gently insert the folded cup as you would a tampon. 3)When the cup is inside, it will pop open. 4)Use it up to 12 hours. 5)To remove it, reach & grip the base of the cup. Pinch the base & take it out gently. Empty it into the toilet & rinse with water and re-insert!

How do I know if a menstrual cup is right for me?

Ruby Cup is great for anyone, regardless of age or if you've been intimate with someone. It's the best period solution for anybody who wants to have healthy, hassle-free periods that don’t cost the Earth. Our menstrual cups are ideal for teenagers, young women, mums, pre-menopausal women, anyone who menstruates!

How does the menstrual cup donation program work?

When you buy a Ruby Cup, a second cup is shipped to our team of trainers and partners in one of our programme countries around the world. We have been working with local organisation since 2012 to help girls get sound education about their bodies and a Ruby Cup to help them manage their period in safety, privacy and with dignity. The Ruby Cup trainers and partners help teach girls and women about menstrual care and reproductive health. They demonstrate how to use the cups, debunk harmful menstrual myths and are on hand to give support.
