Ruby Cup is a healthier, more sustainable, cost-effective and eco-friendly alternative to pads and tampons. Made from 100% soft, medical grade silicone, our menstrual cup is safe, comfortable and hygienic and it is reusable for up to 10 years.

Why switch?

  • Life-changing: 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.
  • Eco-friendly: 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.
  • Affordable: 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%.
  • Less fuss: 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.
  • Healthy: Ruby Cups are made from 100% medical-grade, soft silicone and are blissfully free from plastics, latex, toxins and bleaches.

Ruby Cup is always accompanied by an organic cotton bag for storage and a small booklet with instructions.

Ruby Cup is available in the sizes small and medium. Choose small when you have a light flow and medium when you have a medium to heavy flow.

    I wanted to write and say that I wish I had known about this cup before now, because I can only imagine how much time I would’ve used doing more interesting things than staying home and moaning over my cramps.

    I started my period at 9 years old, and I’ve had HORRENDOUS cramps all my life. This first period with the Ruby cup was the most cramp-free I’ve ever been. It was amazing. I actually forgot I was having a period a couple of times. I could wear the cup the entire day at work, and not worry about it at all until I got home. Plus, no leaking whatsoever over night.

    How much money would I have saved throughout my teens and 20s? How much time and how much trash would I have saved?

    I have had my Ruby Cup for almost a year now, and can’t ever imagine going back to using anything else. Why did I only found out about menstrual cups a year ago! They make everything at that time of the month easier. Not only is it convenient and easy, but you don’t worry about leaks or showing or getting caught out, or having to worry about sleeping in the right position.

    I particularly love the Ruby Cup over other menstrual cups (I’ve tried one other). I’ve never had a problem with it, although I prefer the smaller size as the medium is a little bit too big for me, and the smaller is much more comfortable. As some others have mentioned, if you don’t like the idea of some slight staining, get a coloured one.

    Any ladies out there thinking about trying it out, I say go for it! I’ve only had good, positive experiences, and there is not a bad thing I can say about them.

    I’ve had my Ruby Cup for about 4 months now and I feel like it’s already paid for itself. The cost of disposable products is really outrageous. I am SO glad I’m not producing all that waste too. The cup is so comfortable I can’t feel it. I work out with it and go hiking with zero problems. I have worn the cup for a little more than 12 hours without leaks. This is a great product and I would buy more! I also love that a girl in Kenya is helped every time one of these cups is purchased. Genius idea!
