Last long
Color: BLACKEST BLACK, Size: 0.24 Fl Oz (Pack of 1)
Absolutely love this Maybelline mascara! It makes my lashes look longer, fuller, and more defined without clumping. The formula lasts all day and doesn’t smudge easily. It’s affordable, easy to apply, and gives such a beautiful lash look.”

Good quality but slightly loose cotton
Size: 100 Count (Pack of 1)
This product is great for removing eye makeup and absorbs micellar water well. The cotton round is thick and just the right size for both eyes. However, the cotton sometimes comes undone when my hangnails get stuck on it. It's also easy to tear apart if you pull on it.
