Who it's for
Perfect for individuals who are nervous about reaching for or breaking the seal of a traditional cup.

How it compares
While most cups require you to pinch the base to break the seal, the Flex Cup does this automatically when you pull the stem. This mechanical advantage sets it apart from brands like Saalt or DivaCup, which rely on manual manipulation. However, the moving part in the stem requires slightly more diligent cleaning than a solid-piece cup.
How to use it
- Clean the cup thoroughly before your cycle begins in 2026.
- Fold the cup and insert, ensuring the pull-string is threaded through the bottom.
- To remove, simply hook your finger through the pull-string loop.
- Slowly pull down; the stem will slide through the base and break the suction.
- Empty, wash, and reinsert as needed.
"The pull-tab on the Flex Cup is a game-changer; I never have to worry about the seal being too strong to break." — Verified buyer
Sustainability & ethics
The Flex Co. is committed to reducing the billions of tampons and pads that end up in landfills each year. By providing a cup that is actually easy to use, they facilitate a permanent shift toward sustainable period care for those who previously found cups too difficult.
Pro tip
Don't pull the string too fast; a slow, steady pull allows the seal to break gently and prevents any splashing.
