It's the perfect tool for shaping my nails and keeping them healthy. The double-sided file is great for both natural and artificial nails, and it's so easy to use. I also love how compact and disposable these files are - I can throw them in my purse for on-the-go touch-ups!

Finally a Nail File That Supports Healthy Growth!

I’ve been trying to grow out my nails after quitting tips and dips, and it hasn’t been easy—especially since filing them usually makes things worse. But I found the Onsen Nail Reboot Files on Flip, and they’ve seriously helped! I love that they come in a variety of grits, so I can pick the one that suits the current condition of my nails. Since using these files, I’ve seen a real difference in how fast and strong my nails are growing. If you’re recovering from damaged nails like I am, definitely give these a try. If your nails are still getting acrylics or dips, this might not be for you—but for those of us in recovery mode, it’s a must!

Buena calidad y deja las uñas perfectas

Muy buenas tardes, gente. Ya me llegó mi cajita de limas para uñas (10 unidades) y la verdad estoy muy contenta. Son de buena calidad, económicas y ya las he usado—¡me dejaron las uñas súper bien! Si estás buscando algo práctico, útil y a buen precio, te las recomiendo. ¡Bye!

High-Quality Nail Files – Better Than Glass!

I did a little research on nail file grits, and if you have natural nails, you typically want to use at least a 100 grit or higher, depending on thickness. The lower the grit, the coarser the file. I’ve used these a few times now, and I’m really enjoying them! They work so much better than the glass files or anything else I’ve tried. Definitely a great find!

¡Limas increíbles y prácticas!

Estoy muy contenta con estas limas. Mis uñas son naturales y me encanta hacerme la manicura, así que tener unas limas de buena calidad es importante para mí. Estas son del tamaño perfecto, fáciles de llevar en el bolso, e incluso incluyen una lima pequeña extra, lo cual me encantó. Además, tienen un ligero olor a menta, lo que las hace aún más especiales. Vienen diez (¡más una extra!), y la calidad es excelente. Definitivamente las recomiendo. ¡Estoy feliz con mi compra!

¡Limas de uñas excelentes y de gran calidad!

Estoy muy emocionada con estas limas. Tener una buena lima es esencial para el cuidado de mis uñas naturales, y estas cumplen perfectamente con lo que buscaba. Vienen bien selladas, el color es bonito y lo mejor es que tienen un ligero aroma a menta. No son demasiado gruesas ni demasiado finas, tienen el grosor ideal. Además, el paquete trae 10 limas más una extra, pequeña y perfecta para llevar en la cartera. Me encantaron, definitivamente las recomiendo. ¡Muy buena compra!

Surprisingly Great Basic Nail File

One of the silliest things I’ve ordered on Flip, but it totally works! It’s a nail file—nothing fancy—but I actually like it a lot. It has two grit levels: 120 for tougher jobs like artificial nails, and 180 for smoothing natural nails. Simple, effective, and does exactly what it’s supposed to do.

Perfect Nail Files!

These nail files are amazing! They have the perfect grit—not too rough, not too smooth—making them great for natural nails. The quality is excellent, and they are easy to hold and use. I also love that the pack includes a mini file, perfect for keeping in my purse. Plus, they have a subtle mint scent, which is a nice touch. Definitely a great purchase for anyone who loves doing their nails!

Everyone will want one
These are indeed professional grade nail files which are sturdy and long enough for lots of use and yet treat your nails gently - just the qualities I've come to expect from Onsen. But be warned - as soon as your friends and family know that you have 10 of them (a great cost-effective buy), they'll all want one!

Be Consistent!

This year I committed to spend quality time and education to revive health to my endangered hands and nails. With visible arthritic joints and especially in hands, routine, products and dedication have paid dividends in 6 months...not overnight. I did no dramatic journalist documentation. Just changed my care. To include Onsen nail products. I began with 3 pieces: cuticle cream, nail oil and nail buffer. Expanded to nail files (100% value). I decided NOT to set any timeline because I didn't want to be unrealistic and get discouraged (and give up!). I chose evening before bed. @ 6 months I feel I have recovered at a minimum 75% of my own personal goal. Most successful: cuticles. Which has led to a healing of nail bed and color. Ridges have not entirely disappeared but careful buffing evens out appearance. Growth length is minimal but consistent because I keep growth to ends of nail...but with shaping no biggie. Splits were a big issue. Again, buffing and filing along with close watch on how I physically used my hands (daily). Keeping the splits in the check before they get beyond help. My hardest habit to embrace? ROUTINELY wear gloves when dishwashing, bleach or scouring. 400 count on hand so no excuses...second nature after 6 months... Less expensive products are available. I had to start somewhere and chose Onsen. Personally speaking, I think if consistent care with most OTC nail care is possible in as far as your health allows and we don't expect "miracles" from any one product. Sometimes a blend of several ....it's all about the consistency?

Sehr gute Nagelfeilen

An sich nutze ich Sandblattfeilen auf dünnem Pappstreifen. Glasfeilen mag ich nicht sonderlich zumal meine Naturnaegel fest sind dauert mir das rumgefeile mit Glasfeilen schlichtweg viel zu lange. Die Onsen Feile hat mich direkt überrascht. Ich musste heute eine kleine Stelle eines leider sehr kurz abgebrochenen eher abgerissenen Nagels nachfeilen. Die Länge der Feile gefällt mir sehr gut, sie liegt gut in der Hand, trotz ihrer "Dickte" im Vergleich zur handelsüblichen einfachen Sandblattfeilen ist sie nicht zu dick um sie bei recht kurzem Fingernagel einzusetzen.Sie nimmt sanft genug sofort das weg was man feilen möchte, das zudem so das die entstandene Feilkante schön smooth ist. Mich hat sie absolut überzeugt. Sie wird wohl ein Nachkaufprodukt werden.

Wow! These nail files are AMAZING!

At a time when there are no decent nail files at stores like CVS or Walgreens or any of the places we used to get our nail supplies from - this product is a big relief. As I filed with the white side to shape the nail and then the blue side to even out the nail and ridges, I felt I had done something healthy for my once ragged nails because they looked like they were much healthier and no splitting or breaking in the days that followed.

Quality even if a bit more expensive

Best file I've ever purchased. It's thicker than regular emery boards. It works extremely well yet doesnt mangle my nails. It also lasts longer. I highly recommend this product for quality if you are willing to pay a bit more.

Pricey but worth it

Easy to use and it works incredibly well. The files are good quality and plenty. The buffer is what stands out the most - my nails feel incredibly soft and shiny.
