These are my favorite cotton rounds, and I’ve tried everything from dollar store versions to higher-end “eco” brands. I keep coming back to these. They stay intact and do not separate, even when fully saturated. I use them for micellar water, toner, and nail polish remover, and they hold up well with all three. No fuzz left behind, no pilling, and no pieces sticking to my face. The thickness is just right — not too thin, not overly bulky. They’re soft but durable. I also like that one side has a slight texture. It’s not harsh or labeled as “exfoliating,” but it does have a subtle grip that helps with product application without irritating the skin barrier. Compared to cheaper brands that fall apart and more expensive ones that don’t perform any better, these strike the perfect balance of quality and value. Definitely a repeat purchase for me. TL;DR: Soft, durable, no fuzz, and don’t fall apart. Perfect thickness for toner, micellar water, and nail polish remover. My consistent repurchase.
