Care Instructions
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
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
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.
