Menstrual cups are hygiene products designed to collect menstrual fluid. Typically made from medical-grade silicone, they are a small, flexible, bell-shaped device that is inserted into the vagina. Unlike tampons or pads that absorb fluid, menstrual cups create a seal to collect it, allowing for up to 12 hours of leak-free protection. They are a popular and eco-friendly alternative to disposable products, as one cup can last for several years with proper care, reducing waste and long-term costs.
