Care Instructions

Ruby Cup Menstrual Cup:

* Before/after your period

Boil your menstrual cup in a pan or in a Ruby Sterilizer filled with water for 2–3 minutes.

* During your period

Simply empty your cup, rinse under clean running water, reinsert and go! In a public toilet, use a bottle of water to rinse your cup over the toilet. Or wipe clean with dry or damp toilet paper, then reinsert.

Wear. Rinse. Repeat. Simple!

Ruby Cup Period Underwear:

Our period pants are built to last. Care for them easily with these simple steps:

  • Wash on a cold wash and hang to air dry.
  • Avoid fabric softener and bleach.
  • Steer clear of tumble drying, or ironing.

Social Impact

Periods shouldn’t stop anyone from living their best life. That’s why, for every Ruby Cup sold, we donate one to someone facing period poverty around the world. Thanks to our community and NGO partners, we’ve donated over 150,000 cups so far! Plus, 2% of every Ruby Cup period pants sale goes to a Learning Centre nursery in Kisumu, Kenya, built with our long-time partners, the Golden Girls Foundation, supporting early education and nurturing young minds.

The Ruby Standard

We say no to nasties. Free from BPA, latex and toxins, Ruby Cup offers a reliable and eco-friendly solution for your monthly cycle — crafted from safe and hygienic medical-grade silicone. Because your safety comes first, we treat Ruby Cup with the same rigorous standards as a Class II medical device. Our silicone meets strict European requirements and undergoes voluntary testing for biocompatibility, cytotoxicity, irritation, and sensitisation.
For full transparency, the SGS reports below show that Ruby Cup passed independent tests for VOM (Volatile Organic Materials) and Siloxanes, confirming that our medical-grade silicone is clean, stable and free from harmful residues.

What are the benefits of using a Ruby Cup?

A Ruby Cup is a menstrual cup that comes with a generous handful of benefits that traditional methods just can’t offer. Here are just a few:

*Eco-friendly: a Ruby Cup can be re-used for up to 10 years;

*Affordable: because a Ruby Cup lasts up to 10 years, you’ll rake in long-term savings of more than 95% compared to disposable period products;

*Less fuss: a Ruby Cup has 3 times the capacity of a super tampon. Depending on the heaviness of the menstrual flow it can be worn up to 8 hours. You have everything you need in one simple product;

*Healthy: the Ruby Cups are made from 100% medical-grade, soft silicone and are free from plastics, latex, toxins and bleaches. As they collect, but don't absorb the menstrual flow, the vaginal flora stays intact;

*Life-changing: we call it the ‘Buy One, Give One’ programme. For every cup we sell, we’ll donate one to a girl or woman without access to menstrual care product.

How do I use the Ruby Sterilizer?

Here's how to use your Ruby Sterilizer:

Put your Ruby Cup inside the Ruby Sterilizer, fill with water until it’s about 3⁄4 full and place it in the microwave.
Make sure you do not close the lid completely as that will increase the
pressure from the boiling water and can make it overflow.
Set the microwave time to approximately 3 minutes or enough time to bring the water to a boil and leave it boiling for a few minutes.
After it is boiled, be careful as it can be hot. Grab it by the ears when you remove it from the microwave.
Let the water cool down a bit before you empty it and take out Ruby Cup, which is now disinfected and ready for your next period.
No matter where you decide to use the Ruby Sterilizer, please make sure to leave the lid open to create a steam hole.

I have two or more Ruby Cups, can I boil them in the Ruby Sterilizer at the same time?

No, you have to boil them one after the other to ensure both of them are disinfected and that you can handle them safely after the boiling process.

How do I set the Microwave for the Ruby Sterilizer?

That depends a little on your microwave. You may need to experiment until you find the right settings which will boil your cup inside the Ruby Sterilizer without overflowing too much. However, in most cases, a little water will flow out of the Sterilizer and this is normal.

Is the Ruby Sterilizer vegan?

Yes! Our colorful range of Ruby Sterilizers are all registered with the Vegan Society. This means they don’t contain any animal-derived ingredients and the products or materials haven’t been tested on animals. Period.
