Meet Javi
I'm Javi and I've struggled with the habit for years, trying everything from bitter polishes to fidget toys and gloves — nothing worked. Most solutions were too harsh, too obvious, or just ineffective. I realized I needed a PHYSICAL BARRIER.
So I created Nail Jail: an invisible, non-invasive, and non-toxic way to finally quit. What started as a personal fix is now helping hundreds break the habit with confidence. If you’re ready to stop biting for good — you’re not alone, and Nail Jail is here to help.
HOW IT WORKS?
01 . Prep Nail
Push back cuticles with bamboo stick, buff the nail surface, and file your nails
02. Apply Glue
Apply to inside/concave side of the nail, one drop on the bottom half should do the trick
03. Apply Nail Jail
Align Nail Jail to nail bed and firmly press for 15-20 seconds until firmly secured
04. Trim and File
Enjoy unbiteable natural looking nails thanks to Nail Jail's discreet design–you won't even know they're there!
Let customers speak for us
Nail beds have come a long way, really stoked to keep this progress going in my habit-breaking journey
I swear, this is the only thing that has ever gotten my boyfriend to stop biting his nails. I’ve never seen his nails so long and they aren’t little nubs anymore like how they used to look like and trust me, they were nubs. Now his nails look even better than mine! Definitely will be telling more people about this.
Was hesitant to try at first but my nails look healthy and long for the first time in years
Not clunky or noticeable. I NEEDED something to help break the habit.
The NailJail set protected my nails from constant picking and biting. My nails were able to grow back and I haven’t seen them this long in years!
I was Always so worried about how my nails look until I started using this product. I was worried about going on first dates because of the girls seeing my nails but now I don’t have to worry anymore thank you NAILJAIL!!
CONSEQUENCES OF BITING YOUR NAILS, IT...
1. ... wrecks your Health by Introducing GERMS, VIRUSES, and BACTERIA
Nail biting isn’t just a bad habit—it’s a health risk. Your nails are bacteria hotspots, and every bite gives germs a direct path into your body.Hands touch everything—phones, doorknobs, bathroom sinks—and under your nails, bacteria like E. coli thrive. Chewing them means damaging your skin and compromising your immune system.Nail Jail helps break the habit and protect your health—fewer hangnails, stronger nails, and far less exposure to everyday grime.
2. ... causes GAPS IN YOUR TEETH and a CROOKED SMILE
Nail biting doesn’t just damage your nails—it can quietly ruin your smile. The pressure can shift teeth out of place, causing gaps, crookedness, and alignment issues.Teeth aren’t built for that kind of stress. Biting wears down enamel, strains your jaw, and gradually pushes everything out of line—leading to a crooked smile and costly dental fixes.Nail Jail helps you quit before the damage builds. A simple tool with real impact—for your nails, your teeth, and your confidence.
3. ... WEARS DOWN YOUR ENAMEL
Nail biting isn’t just a nervous habit—it’s hard on your teeth. Every time you chew, you’re putting pressure on them that wears down enamel, chips edges, and weakens the foundation of your smile. Teeth are strong, but constant biting causes microfractures, sensitivity, and uneven wear—especially in the front. The more you bite, the more damage you do to the enamel that protects against decay.That’s where Nail Jail helps. It’s a small tool with a big purpose—stopping the habit before it leads to lasting dental problems.
4. ... can Lead to SKIN INFECTIONS or much Worse
Nail biting might seem harmless, but it can spiral into something much worse. Every time you chew the skin around your nails, you create tiny wounds—perfect for bacteria to slip in.That’s how infections like paronychia start. Redness, swelling, and pus may follow, often requiring antibiotics or even minor surgery. In more extreme cases, the infection can spread deep into the finger.And yes—when left untreated, it can lead to permanent damage or even amputation.

Great
They actually do work pretty well, the only problem I have was it was a little painful to push the cuticle back to place the nail. Other than that it worked perfectly! The glue is strong enough that I can use my finger nails to pry things apart without them coming off
