Great organic cotton rounds
Size: 300 Count (Pack of 3)
I use these every day after I wash my face, I've been buying these for years. Works great, high quality cotton rounds that maintain structural integrity during use, no issues with my sensitive skin, perfect thickness and consistency. Good price and this three-pack lasts ages. Best option for cotton rounds.

High quality
Size: 100 Count (Pack of 1)
These are great for sensitive skin. They have a really soft, gentle texture that I haven't found in any other cotton rounds. And they are durable---the layers don't separate---they don't fall apart. These are high quality. Highly recommend.
