Menstrual care solution that collects rather than absorbs, designed for up to 12 hours of wear and reduced irritation. Confidence and comfort for people seeking a reusable alternative that supports natural pH. Is AllMatters Menstrual Cup the right reusable option for those who have given birth vaginally?

⚡ At a Glance
  • Wearing Comfort: Soft medical-grade silicone conforms to anatomy for a secure, gentle fit
  • Best for: People who have given birth vaginally seeking a reusable, low-maintenance period solution
  • Not ideal for: Anyone who prefers single-use pads or tampons or cannot use internal menstrual products

Size B is designed for those who have given birth vaginally and holds roughly three tampons for up to 12 hours. Made from 100% soft medical-grade silicone and supplied with an unbleached organic cotton pouch.


Extended protection - with a three-tampon capacity and up to 12-hour wear

Cup design collects menstrual flow rather than absorbing it; internal capacity equals about three tampons and forms a seal for extended wear. Medical-grade silicone creates a reliable barrier while allowing low-profile placement.

Fewer daily changes suit busy schedules and overnight use, offering practical, long stretches between emptying.

Comfort for sensitive skin - thanks to 100% medical-grade silicone

Material is soft, biocompatible and free from known allergens after toxicological examination, enabling Allergy Certified status. Smooth silicone reduces friction and avoids the dryness caused by absorbent products.

Gentle contact helps maintain natural vaginal pH and reduces irritation compared with absorbent alternatives.

Sustainable, travel-friendly storage - with an unbleached organic cotton pouch

Each cup comes with an unbleached organic cotton pouch for hygienic transport and discreet storage between cycles. Reusable design eliminates repeated single-use waste.

Pouch keeps the item discreet and portable, while reuse reduces landfill compared with disposable pads and tampons.
