The Cora Ball is a new kind of laundry ball. Inspired by the way coral filters the ocean, the Cora Ball collects our microfibers into fuzz we can see, so we can dispose of microfibers in the right way. At the same time, Cora Ball helps PREVENT microfibers from breaking off your clothes, reducing the total amount of microfibers produced and protecting your clothes. Together, we can keep these microfibers out of our waterways and our ocean. Yes! Just toss the Cora Ball into your washer. It's a simple step that has a big impact wash after wash.
