As an eco-friendly and cost-effective alternative to pads and tampons, there are so many reasons to consider making the switch to menstrual cups.
Good to know
Where do I place my Ruby Cup?
When your cup is correctly inserted, you will not be able to feel it, and there will be no discomfort. Use your finger to push your cup higher or lower until it sits comfortably. Many women find that twisting their cup helps it to sit in the correct place, and that with a little time the silicone material softens with your body heat.
How long does a Ruby Cup last?
5 years
What are period pants?

What are your shipping and delivery times?
