## Description

Product description You do not need to lure it. The best way to stop biting your nails is to draw a sharp line on that bad habit or, more precisely... a sharp line on your fingers. Raylex has the bitter taste of grapefruit bark. Raylex contains a unique combination of citrus bark and denatonium extracts. Denatonium is honoured to be entered in the Records Book as the bittest substance in the world. Exactly what you need to stop biting your nails. Directions Apply to the damaged edge of the nail, not the entire nail, and wait for the liquid to be absorbed.

Review: Really does work - I'm surprised as other products were not great, this truly works.
Review: Only thing I've found which works! - So I've been a nail biter for 45 years! I have a stressful job and a long commute and I just find I can destroy my nails really quickly. I've tried many things in the past but never been able to kick the habit so to speak. Although this was expensive I thought I would give it a try. So 6 weeks later, I'm no longer having to apply it daily. It was fairly disgusting and incredibly bitter, with a taste which lingers in your mouth, unlike some of the other products where its almost a contact taste and once you get past that its game on. This one really made you think twice before trying to bite. Of course, the downside is it does transfer to other items so you just need to be careful. Anyway although the last 2 weeks I haven't had to use the product although I did have a relapse and bit one nail but since then I seem to have broken the habit. Time will tell and I will try and update this to let you know how I get on, but I can definitely say that this has been the best product so far that I've found and for me has been the only one which has worked. I am really pleased 5/10 - Just wanted to update that I think I have broken the habit after 40 years - have not had to reapply this for 4 weeks now and I've not bitten so I think this has really worked. 7/12 - Still working well - occasionally on a long car journey i reapply just to stop the boredom habit creeping back but it really has helped me kick the habit!

## Questions & Answers

**Q: Can this be used on clothes to prevent child sucking/chewing clothes**
A: Possibly - it transfers the coating from the nib in the pen - doesn’t get too wet or feel damp but it’s effective on nails - can’t see why it wouldn’t work on clothes but might not be as strong as on nails

**Q: From the picture in the box the product looks like a pen. Is that the case? If yes do you need to refill it or you need to buy a new one when done?**
A: Yes it’s a pen with a felt nib which stays filled with the liquid - it doesn’t really feel wet or damp though. When it runs out you just buy a new one - mine is still going after 3 years

### ⭐⭐⭐⭐⭐ "Does exactly what it claims"
*by P***M on 18 July 2017*

I bought one of these for a friend, who has always bitten her nails, almost down to the cuticle, and has done this since we were kids (40+ years) she has tried so many different products, without success, but this has really worked, and her nails are actually growing, so much so, she is wanting to buy more..!! so I would highly recommend this product 👍🏼
