soft and excellent cleaning results
Style: 100ct
Although these makeup remover pads aren't particularly thick or large, for my purposes—which involve using them solely to remove eye makeup—they are quite soft and cause no irritation to the delicate skin around the eyes. All in all, I am very satisfied with them.

Good for Lashes, Just Wish They Were Bigger
These wipes are nice and work well for what I mainly use them for. I’ve been using them mostly for lash cleanup, and they do a good job without being too harsh. They feel gentle on the skin, and the material is soft enough for the eye area, which I appreciate. They’re easy to use and come pre-soaked, so it’s quick and convenient. My only real complaint is that I wish they were thicker and a bit bigger. For small areas like lashes, they’re great—but if you’re trying to remove a full face of makeup, you’ll probably need to use a few more than expected. Overall, they’re effective and convenient, especially for lighter use or targeted areas, but I do wish they had a little more size and thickness to them.
