I did not get these for its intended purpose. I actually got my nipples pierced and used these when I needed to soak with saline solution. I also used them as a bandage for my knee and it worked perfectly compared to a regular bandage. The curve of them made them fit my knee a lot better. So for that I give the product 5 stars. But since I’m not breastfeeding I can’t say how absorbent they are.
