Changing the world – one period at a time
Less period waste
On average, every menstruating person uses around 16,800 period products in their lifetime. Disposable products alone generate more than 20,000 tons of waste in Germany alone.
Sustainable alternatives, such as period panties, can completely replace disposable products such as tampons and pads.
They are
- washable
- made from sustainable materials and
- reusable
Lower water consumption
Although the Period Panty needs to be washed, water consumption is minimal compared to making disposable products.
