How does the Raylex® pen work?

We won’t beat about the bush. If you want to stop biting your nails, this is best achieved with a rap on the fingers... or in this case with a “lick of the fingers”.

Raylex® has the bitter taste of grapefruit peel. Raylex® contains a unique combination of citrus peel extract and denatonium. Denatonium has the honour of being mentioned in the Guiness Book of World Records as the bitterest substance on earth: ideal to help you kick the habit of nail biting.
