How many ooias do I need?Updated 2 months ago

The ooia period underwear is designed to hold 1-6 tampons or 10-30ml of fluid, depending on the model. How many and when you use ooia period underwear depends entirely on your needs - your preferences, your plans, the intensity of your bleeding, and many other factors. To completely cover one period, you will need about 5 ooia Period Panties - assuming you wear one at night, one during the day, and wash the used panties after two days.
