Description Bitener Anti Nail Bite Pen assists in curbing the desire for cuticle and nail biting, as it contains Bitrex, the most bitter substance in the world. Its strong flavour acts as a deterrent against the habit. Bitener is formulated to take advantage of the 21-day habit formation routine. While the process of changing a habit can be challenging and vary depending on the individual, the included 3ml of liquid is enough to last longer than the recommended 21 days. Bitener is a topical, non-glossy nail treatment which helps to interrupt the impulse to bite nails with just a single application per day. Author: John BrennanView all posts by John Brennan
