Ruby Cup Menstrual Cup Review

The Ruby Cup is a menstrual cup brand founded in 2011 by three amazing people; Maxie Matthiessen, Veronica D’Souza and Julie Weigaard Kjær.

Ruby Cup Menstrual Cup Review

Ruby Cup isn’t just your average company, though. They run a program called ‘Buy one, give one’ in which they donate one of their own cups to a girl in East Africa. The idea behind it is to keep girls in school. Many girls in Africa miss out on education because of their period. Because they can’t afford pads, they have no way to manage their period. Shame from leaking means many drop out of school entirely.

Ruby Cup Keeps Girls In School

With the ‘Buy one, give one’ initiative, they are able to equip the girls with their own ruby cup. Not only that, but they actually have people out on the ground teaching them how to use it. Through this amazing effort, communities called Ruby Cup Clubs have formed. These clubs give the girls and women an open space to talk about menstruation and their reproductive health. Such a simple gesture has helped to empower these individuals.

Purple & Blue Ruby Cup

Ruby Cup Specs

The Ruby Cup is made with 100% medical grade silicone and comes in 4 colours; clear, blue, purple and pink. There are two sizes available; size small and medium.

They originally were only available in medium and marketed as a ‘one-size’ cup. But after feedback from the community, a smaller cup was created.

Although made from the same materials, the two sizes are a different firmness, with the small being softer. The silicone is frosted/partially opaque with a smooth, non tacky feel to it. Both of the cups are different sizes.


Total Length 68mm | Stem 17mm | Cup 51mm

Capacity to rim 34ml | to airholes 24ml


Total Length 65mm | Stem 19mm | Cup 46mm

Capacity to rim 24ml | to airholes 19ml

Medium & Small Ruby Cup

There are 4 airholes just under the lip of the rim which go straight through. The holes are quite small. Inside the cup there are fill level markings, and above those the words ‘Ruby Cup’ are embossed. The inside of the cup feels tacky which is different to the smooth finish on the outside.

The stem is thick and firm, and also has raised dimples all over it. On the base of the cup, there are 3 smooth, slightly raised ridges.

Safe, healthy, cost-saving and reusable.


Each cup comes with its own cotton drawstring pouch, with the drawstring colour coded to the cup colour.

My Thoughts On The Ruby Cup

I first started out with this cup when it was only a ‘one size’ and I really didn’t like it. No matter what I did, I just didn’t ever feel comfortable wearing the Ruby Cup. I always felt it inside my vagina and had pressure on my bladder. Repositioning it backwards towards my spine didn’t help. So I had written it off, and that’s why I didn’t post a review.

That was until the sizes were changed and a small was released. The small works well for me because of it being softer and smaller. The only downside is the capacity during my heavy days, but it’s no big deal emptying more often.

I really enjoy the feel of the silicone and the quality of the cup is fantastic. There are no obvious seams and the cup is easy to clean.

Would I recommend the Ruby Cup? Yes – I think the cups are very well made. I also absolutely love the fact they donate cups to girls in Africa and provide education using them.

    I love how they donate a cup for each one purchased. I would love a comparison video with this one.

    I wanted to try the Ruby Cup right from the start, cos I liked the “Buy One, Give One” scheme. But I thought it was too expensive. I really should have just gone ahead and bought it then because now, six cups (and a huge hole in my pocket) later, I discovered that Ruby is the one that works best for me. Better late than never I guess. And a girl in Africa also benefits.

    A great informative review. I don’t use menstrual cups but I’m really digging this company’s buy one give one scheme, a fantastic thing to do.

    I’ve not used a ruby cup….but they seem a good company to donate cups to girls in africa and that they listen to the customers and take their feedback into consideration when taking the company forwards. x x
