Care
- Wash your period panty before first use to activate its full absorbency
- and by hand with cold water – this helps dissolve the blood.
- Then simply toss it in with similarly coloured laundry on your washing machine’s gentle cycle.
- Wash your panty at 40 degrees and a maximum of 800 spins (ideally in a laundry bag).
- It’s best to use a mild detergent and avoid fabric softener to protect the fibres of your panty and preserve maximum absorbency.
- Then simply let it air dry.
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. Single-use products alone generate more than 20,000 tonnes of waste in Germany*.Sustainable alternatives like period panties can completely replace single-use products such as tampons and pads.
They are:
- washable
- tested for harmful substances
- reusable
Lower Water Consumption
Although period panties need to be washed, water consumption is minimal compared to the production of single-use products.
