That applicator is a throwback to the 70s and 80s. We only had those. Or lip brushes. I used art brushes back then for blush and eyeshadow. There was really no such thing as "makeup" brushes back then, except for what came with the product, and those sucked, felt scratchy, didn’t blend out anything.
Yeah I remember it from being a kid in the 90’s, it’s not a tool I like. It’s amazing how far things have come with cosmetics. The lip applicator I like but that eye sponge thing not so much.
