You will get black cotton pads. That way, you don’t have to do a special whitewash.
6 reusable pads
1 mesh bag
How do I prepare to reuse the pads?
You can just throw the pads in the washing machine. Washing at 30-40° C should be sufficient if they are not very dirty. Otherwise, wash at 60° degrees. You can avoid losing them by putting them in the mesh bag.
Of course, there is no need to put them in the washing machine. In case you might be worried about not having a clean pad left because of not having a full laundry basket in time, for example. No problem. You can also wash the pads by hand. Better even, as they will last a bit longer that way.
