Soft, lint-free, and gentle, just a bit thin
Size: 100 Count (Pack of 3), Set name: Classic
These Cliganic cotton rounds are very soft, gentle on the skin, and truly lint-free. I use them daily for makeup removal and skincare, and they feel high quality and comfortable, even on sensitive skin. I also appreciate that they’re made from 100% pure cotton and are hypoallergenic. They do a great job removing makeup and applying toner without falling apart or leaving residue behind. The quantity is excellent as well, 300 rounds is a great value and lasts a long time. The only reason I’m giving four stars instead of five is that the pads are a bit thin. They still work well, but I sometimes need to use two instead of one, especially for heavier makeup.
Overall, these are reliable, gentle cotton rounds that perform well and are a great option for everyday skincare. I would definitely purchase them again.
