Review: It just plain works - Six weeks ago, my wife persuaded me to try Fidyn No Bite, after all my nails were down to, or almost to, the quick. I was amazed a how well it worked, because, frankly, it’s not all that terrible, and besides, I was pretty lax about using it. After the first application, my hands went to my mouth a half dozen times or so, and the taste would startle me into putting my hand down. It wears out after several hours, so you have to reapply, which I did faithfully for maybe a day and a half. After that I only used it when I remembered, which was, like, every other day, then every third day, then once a week, and now never. But I found that when I put my hand to my mouth, I would remember the taste, even though the taste wasn’t actually there. A complete success, and I have a lot left, in case I ever start biting again. Great product. Review: 👍🏼 - Helped get rid of my habit. ## Features - 【Moderate Bitterness That Works Just Right】Not too bitter to make you sick yet bitter enough to discourage you from biting your nails (or putting fingers in the mouth) ever again. The amount of the bitter substance in the product is carefully measured to suit the taste buds of most people. Effective for more than 85% of users, for those who do not see effect, hassle free for help is guaranteed. - 【The Bitter Taste Can Stay On For As Long As You Want】One application will let the bitter taste stay for several hours and several applications for a whole day. The taste will not rinse off after normal hand washes. However, if you really want to get rid of the bad taste immediately (such as before eating your meal), a thorough soap wash will rid your hands of the product. With Fidyn no bite nail polish, you can get that bad taste whenever you need it but never let it ruin your whole day. - 【Safe For Children, Toddlers and Adults】Bitrex solution is the chemical that most brands use as a deterrent to nail biting/finger sucking habit. However, we choose to get the bitterness from mostly organic plants such as bitter melon and licorice and we use the least amount of Bitrex possible. These plant based bitter substances are natural - non toxic and make the Fidyn nail biting polish safe and effective for everyone. - 【One Bottle Is All You Need】It takes persistence to quit a bad habit and the average time to do so is usually around 2-3 months for most people. That is why our Fidyn nail biting polish contains 10 ml/0.34 fl.oz. of product which is enough for more than 3 months usage. One little bottle is all you need. - 【Do our best for you】We will do our best for you. We recognize that not every customer will have the same reaction to the bitter taste, but we believe our product + our services will be great for you. If you are not happy with our product and services, or if your habit is still not gone after using our bitter nail polish, contact our CS team for a hassle free help. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08VNQ3SV4 | | Best Sellers Rank | #60,579 in Beauty & Personal Care ( See Top 100 in Beauty & Personal Care ) #733 in Nail Polish | | Customer Reviews | 4.0 4.0 out of 5 stars (1,494) | | Manufacturer | Fidyn | | Package Dimensions | 3.35 x 1.18 x 1.14 inches; 0.35 ounces | | UPC | 667176090060 | ## Product Details - **Brand:** Fidyn - **Item Form:** Liquid - **Item Weight:** 10 Grams - **Liquid Volume:** 0.34 Milliliters - **Specialty:** natural ## Images ![No Bite Nail Polish – Nail Biting Treatment with Bitter Polish to Help Adults to Quit Nail Biting For Life and Also Help Stop Thumb Sucking For Kids - 10 ml/0.34 fl. oz - Image 1](https://m.media-amazon.com/images/I/61gxpaSpIcL.jpg) ## Questions & Answers **Q: Where is this made** A: This product was made in China, you could find the details in package. I just wanted to let you know that we're available any time you have a question or suggestion for our product. **Q: Some reviews said doesn't work and some said works. Could someone tell me your experience？** A: Regarding the bitter taste of the nail polish, we deliberately lowered the degree of bitterness for safety's sake, yet actually it is still very bitter for most people. And we know that one kind of bitterness would not suit ALL people, since people do have different perception of bitterness. Our product development team had tested thousands of people, and concluded that for the same degree of bitterness, some will say it's too bitter while others will say, it is not bitter at all. That's why we promise Money-Back to customers who are not satisfied with the bitterness of our product. At the same time, if the polish is too bitter, it may cause adverse reactions such as nausea and vomiting, especially among children, as you know, safety is also very crucial, so please undertand why we decided to lower the bitterness. **Q: Could anyone share the Bitter feeling? Can I use it for mischief？** A: For now, the Bitter is level 1, however, many customers feedback not enough, so we have improve it to level 2 and will coming soon. For mischief, actually, for Adults, it's OK, they will mischief back to you. But for Kids, you'd better not do it. **Q: Is this matte or glossy?** A: It’s just liquid. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It just plain works *by G***S on August 5, 2021* Six weeks ago, my wife persuaded me to try Fidyn No Bite, after all my nails were down to, or almost to, the quick.

Great product. ### ⭐⭐⭐⭐⭐ 👍🏼 *by N***H on January 8, 2026* Helped get rid of my habit. ### ⭐⭐⭐⭐ Helpful for Breaking the Habit *by S***Y on September 23, 2025* My son has been struggling with nail biting for a long time, and this product really helped me reduce the urge. The bitter taste works effectively, and it’s easy to apply like regular nail polish. After a few days, I noticed I was more aware of my habit and stopped biting as much. The only reason I’m giving 4 stars instead of 5 is it needs reapplying fairly often. Overall, a very useful product for anyone trying to stop nail biting or thumb sucking. ## Frequently Bought Together - Fidyn No Bite Nail Polish, Nail Biting Treatment with Bitter Polish to Help Quit Nail Biting For Life and Also Help Stop Thumb Sucking (10ml) - Nail-Aid Keratin 3 Day Growth Nail Treatment & Strengthener, Clear, 0.55 Fl Oz - Onyx Professional Stop the Bite Nail Biting Deterrent Polish 0.5 Fl Oz - Helps Nails Grow & Can be Used as a Top or Base Coat --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/299918936-no-bite-nail-polish-nail-biting-treatment-with-bitter-polish](https://www.desertcart.hr/products/299918936-no-bite-nail-polish-nail-biting-treatment-with-bitter-polish) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-17*
