Amazing!
I have tried numerous expensive products to fix my severely damaged nails that were perpetually splitting. I have been using this product for 2 days and the results are remarkable.m! My nails look and feel so much healthier. I will be throwing away all of the other products that were ineffective!

Great Product
I read a ton of reviews including the negative ones. I was on the fence but my nails and cuticles were such a mess, I finally ordered the kit. I had been trying a variety of products before this. None really worked. I was thinking about going to get my artificial nails back on after growing them out during the pandemic, but I tried this first. It's been 10 days. Before I get into my hands, let me tell you about my toenails. I've used the nail file and buffer on them and they look amazing after one use. I've never seen them look this great. The cuticles are smooth and it looks like I spend a lot of time taking care of them. The edges are so smooth, nothing like you get at the nail salon. Let me address the cuticle cream. It does not leave your hands feeling sticky. It dries and feels like you have the nail bed to skin "sealed". I have no desire to pick at them. It seems to seal the skin so that it won't peel giving me the urge to pull the peel off. That is a big plus for me. I would buy this just to get the cuticle cream. It's lightweight so not really a cream--more like a light weight lotion that heals. The nail file quickly gets your nails in shape. Much faster than the files I use. It also worked very well on my toenails. Quick. The buffer also works quickly. Follow the instructions on how many swipes to make. This system for the price is the best I can find. You would have to really hunt everywhere to put individual items together that were as good as this system--and it would cost much more. The bonus for me besides the healing cuticle cream is now I can do my toenails in a matter of minutes and they've never looked better. Love this system.

Amazing results - instantly!
For many years, I've kept my fingernails trimmed very short for convenience and practicality for typing, etc. With that, I haven't paid much attention to whether or not they look good. For one thing, I don't like to wear nail polish - it's messy, doesn't last, and isn't good for nail health. I've been a little jealous of my friends' nails, but a lot of them wear acrylics and I didn't want to do that, either. So, I decided to try buffing, and after some research, I ordered the Onsen Secret Japanese Nail Buffer and Shine Kit. It came yesterday, and I used it immediately: file, cuticle cream, and buffer. What a difference! It was so easy to use. The file was great - didn't leave my nails rough at all. The cuticle cream (just a tiny drop on each nailbed) was soothing and absorbed beautifully. And the buffer - WOW!!! I used it as directed, first the silver side, then the green, and then a final polishing buff with the white side. I can't believe the difference in the appearance of my nails! In less than ten minutes, they went from ridged and dull to smooth and glowing with a nice sheen! At age 72, I've finally found a nail care regimen that I not only can live with, but which really shows good results. Yes, I'll still keep my nails short, but now they can look very nice anyway. THANK YOU FOR THIS PRODUCT! I will use it faithfully from here on out. (I wish I had taken a "before" picture of my nails so you could really see the difference this product has made with just ONE use!)

Great product !!
So far I like it! Will update 4 weeks.mstill,puzzled how sanding our ridges is part of the strengthening instructions since makes nail thinner.

It Actually Works!
Idk how, but this actually made my weak, paper thin nails stronger! They were all jacked up and thinned down after too many Dremel removals of gel polish. I’m still growing them out and keeping them short, but the little bit above my nail bed feels really strong. And they look so pretty and shiny after using the buffing cube. I try to use the cuticle cream every day, though I don’t keep up with the buffing. I am definitely keeping this in my collection of self care products.

Amazing Kit!
I bought this in hoped that I could clean up my nails so they looked good and healthy. I do not like nail polish much and when I use it or anything else (gel, acrylics, etc), my nails get worse. They are already thin to begin with. The cost was slightly less than a local manicure. And I was skeptical, but I want pretty hands for going out on my 10th Anniversary. So it was try this or knuckle down for a manicure and the effects of polish in the weeks after. Package arrived last night and I put everything to use. Cleaned up the nails with the file, employed the buffer, and used the cuticle cream. In one use, AMAZING difference. First and foremost, my nails look so much better, much healthier. I had some ridging and suffer from frequent breaking. After working the steps, you would never see it. The ridges are almost gone and the few lines I have are almost invisible. Secondly, that buffer. Holy smokes! After the third (white) buffer, my nails are shiny. They look like I have applied clear shiny polish on them! In fact, my fingernails appear like I just had a natural manicure done on them. Clean, neat, pretty, healthy, and shiny. WOW. Sold!!

Good product but EXPENSIVE!
This product works well, but it is not cheap, and I don't know if the cream's formulation is proprietary. The buffer and the file can be purchased for much less, so theoretically, the cost is in the cream, and it's hard to tell if there is something special about it. It seems similar to other nail strengtheners/cuticle creams I have used. I have only been using it a week, so maybe its effect will be greater over the long term, but that remains to be seen.

It really works!
I love having short nails but it's nice to make them look neat as well, I was using a clear nail polish but this is so much better! My nails are smooth and shiny, they look like they have polish on them and they are also growing like crazy. I highly recommend this kit. I've only used it twice so far and my nails look so much better.

Excellent set, my nails look and feel so much better!
Thrilled with this set. My hands tend to be quite dry and I suffer from hangnails. I am really impressed with the cuticle cream! I also was surpised at the size of the tube - I expected it to be much smaller. Definitely a pleasant surprise. My nails look so much better now, and I love the shine I obtain when I use the buffing block. It’s a lovely set and makes doing my nails an enjoyable experience rather than a chore. When I follow the steps in the set, I find that my nails look pretty enough on their own and I don’t have to bother with nail polish. I also appreciate that the buffing block is refillable and the set came with additional refills ( I saw another review mentioned that theirs didn’t come with refills, but mine did). Everything in the set is of excellent quality. As items run out, I will definitely be repurchasing.

Great little nail care set!
I have been using this set for 2 weeks now, and although I will update later on how long-lasting it is, so far so good. I have very weak nails naturally, they are flexible and tend to flake and split from the side edges inwards, and after years of cancer treatments and a chemical menopause, they have now started to show vertical ridges. As I’m still in treatment and not allowed to use nail varnish or remover most of the time, I bought this set in the hope that it would make my nails less embarrassing! The first time I used the buffer, the visible difference was immediate: the beginnings of ridges were smoothed and the nails so shiny they looked as if I had clear nail varnish on them. The shine lasted for a week despite using the cuticle cream on it most nights, until I used the buffer tool again. The cuticle cream is easy to apply and has a light fragrance of garden herbs, and I’m really pleased with how healthy my nails are now looking 👍 In the two weeks I’ve been using the set I haven’t had any splitting or breakage, which is unusual for me but I don’t want to assume this is down to the Onsen products until I’ve used them for a longer period. The buffer surfaces are apparently valid for 10 uses (so 10 weeks if following the box instructions) and it includes a spare set.
