We cannot recommend this period disc enough! The disc provides 12 hours of protection day and night, and is reusable for up to ten years. Comes in two sizes depending on your flow, cervix and needs. Designed to be comfortable and easy to insert and remove. Unlike other period cups, the Saalt Disc doesn't rely on suction to seal, but instead positions behind your pubic bone, and has a custom finger notch that makes removal a breeze. These discs are safe, reusable, reliable and not to mention - not wasteful! They also help maintain your natural pH, allowing your flow to flow without the unknown toxins. It also comes with a sweet carrying bag to take with you on your travels!
