Your tampon was designed by a man. In 1931. And it hasn't changed since.
For almost 100 years - the same design. Built by someone who never used one, never updated by anyone who had. Traditional tampons can fail before they're full. Vertical channels can funnel fluid away from the absorbent core — creating bypass leaks before capacity
IT'S NOT YOUR BODY. IT'S THE DESIGN.
INTRODUCING SEQUEL SPIRAL TAMPONS
Sequel's patented helical channel interrupts the traditional vertical fluid flow path. Instead of funneling fluid away from the core, the spiral is designed to promote even absorption across the full tampon body.
The result:
A tampon that gets it done, so you stop thinking about it.

"AS ATHLETES, WE COULDN'T FIND A TAMPON WE COULD RELY ON. SO WE CREATED ONE."
TWO STANFORD ENGINEERS. ONE OVERDUE FIX.
Amanda Calabrese and Greta Meyer weren't looking to start a company. They were athletes — dealing with the same period product failures every woman deals with. A competition in a swimsuit. A lacrosse game in a white skirt. As engineers, they asked a different question: Why hasn't anyone actually fixed this?
Years of R&D, a patent, and an FDA clearance later — Sequel exists. This tampon wasn't rebranded. It was re-engineered.
Sequel was stress tested first by athletes and designed for every range of motion.

FREQUENTLY ASKED QUESTIONS
Have any more questions? Let us know!
Is the applicator hard to use?
The Sequel applicator is compact, which means it needs to extend before insertion — one extra step vs. a traditional applicator. Each box comes with step by step instructions for use, and our team to support if you have any product questions.
Will it actually feel different?
The spiral is designed to promote even absorption, and is designed to be more comfortable. Customers consistently describe it as feeling less noticeable — which is exactly the point.
Is it safe? Are the materials clean?
Yes — FDA 510(k) cleared as a Class 2 medical device, OEKO-TEX Standard 100 certified, and synthetic dye-free. Every component is independently tested.
