MAC Duo Brush-On is a black lash adhesive in a small bottle with a built-in brush applicator. The brush lets you paint a thin line of glue straight onto the lash band or your lash line, which is easier to control than squeeze tubes. It dries dark and blends with black eyeliner, so it suits people who wear liner and want a tidy, low-fuss application. Against drugstore brush-on glues it is a premium pick; reviewers rate the control and the dark finish, but some find the hold weaker than stronger-hold formulas and the small bottle runs out quickly with daily use.

Reviewers like the brush applicator and the black finish that blends with eyeliner. Many say the hold is fine for a day or an evening but not the strongest, and daily users note the bottle goes quickly.
