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.
