All brands of menstrual cups we bring in are made of high quality medical-grade silicone. Quality matters to us because we don't want to insert any dubious materials into the vagina! We do not stock any menstrual cups that are made of unknown quality materials, or are knock-offs of established brands. Although such cups can be purchased at very low prices on websites such as AliExpress, we only wish to bring in the highest quality items for our customers.
All the brands of cups that we carry are registered with the FDA in the US. You can refer to this blog post where we discuss FDA approval and registration of menstrual cups. You may also refer to the quality and standards of our cups (in the individual product listings) for your peace of mind.
