Why QUITS?

Nail biting runs on autopilot. You're in a meeting or scrolling your phone, and before you know it you're biting again. QUITS puts a bitter layer on your nails, so the moment one reaches your mouth you notice, and stop.

It dries invisible with no shine, and conditions with keratin and biotin while the habit fades.
