Comfort significantly affects the user experience. A comfortable menstrual cup should have a proper fit, which is related to its shape, size, and material softness. For example, a material that is too hard may cause discomfort or even pain during use, while a soft and flexible material can better conform to the body's natural shape, reducing the feeling of foreign body.

Environmental Friendliness
In an era of growing environmental awareness, the environmental impact of menstrual products has become a major concern. Reusable menstrual cups, compared to disposable pads and tampons, can significantly reduce waste. However, the environmental friendliness of menstrual cups also depends on the materials they are made of. Biodegradable materials, for instance, are more environmentally friendly as they can decompose naturally over time.

Core Question: How Do Performance Differences of Different Materials Affect Consumer Choices?
Consumers often face a dilemma when choosing a menstrual cup, mainly because they are not fully aware of the performance differences between various materials. Does a longer - lasting material mean better value for money? Is a more elastic material more comfortable? And how to balance safety, comfort, and cost when making a choice? These questions are at the heart of consumers' decision - making process.
