    • Shiny nails
Size: 1 Buffer
Review Image by R.M. R.M.
I'm a middle age hetro man and my profession requires me to have good nails. Have used various nail buffers and such over the years and this is by far the best. Takes no time and nails look great. Would definitely reccomend and have purchased several times.

    • Best nail buffer
Size: 1 Buffer
This is the best nail buffer. No polish needed. Perfect to keep around with hand lotion and you have an instant manicure in less than 10 minutes. I can’t get manicures as they damage my nails to much and this works wonderfully and doesn’t cause any damage.

    • This actually works!
Size: 1 Buffer
Review Image by Trish Trish
When I opened the package, I thought, “bummer, this is just a expensive nail buffer block” but then I used it and in less than 5 minutes, I had nice shined nails. It took no time at all to get a nice shine!! Wow! I’m impressed! I figured if the buffer block actually works 20x better than the drug store $4.99 ones, maybe the critical cream is great too. I just bought some so we will see. I’m a very happy customer. ... show more

I’m a nail biter and I bought this nail buffer thinking that if I have nice nails I won’t bite them and screw them up and it worked! I’ve never buffed my nails before but this has numbers on the squares to tell me the order in which to use the different sides! I haven’t bitten my nails in over a week! I will be buying this again! ... show more

    • So good had to buy it as a gift!
Size: 1 Buffer
This leaves nails very shiny. The shine lasts for weeks and I can confirm—it helps nails to grow faster. (It even helped smooth out some of the deeper ridges in my toenails!)

    • Decent block, nothing amazing; don’t use too often or nails will be thinned and damaged

First, note that any buffing block like this, no matter the brand, is damaging to the nails. You’re essentially filing off the nail’s top layer of keratin with a fine sandpaper, then buffing it to a shine. So it certainly shouldn’t be done often, especially if you have naturally thin or brittle nails to begin with. So use sparingly and/or only on very thick and healthy natural nails! That being said, I bought this because after keeping my nails painted with regular polish practically 24/7 for over a year, they started peeling in sheets from the tips, no matter what products, brands, and techniques I tried. I knew I wanted to take a step back from polish and allow the peeling tips to grow out, but still find a way to keep my natural nails looking shiny and smooth without polish. So, I decided to try this buffer once to give my natural nails a “fresh start.” It’s expensive for a single buffing block and I didn’t find that it really performed any better than a cheaper block from a beauty supply store. It gave me a nice smooth feeling and a shine, but nothing super glossy or glass-like. I did go easier with the sanding steps to protect my already-thin nails. The more you sand off, the more shine you’ll likely get (but the more damaging). The initial shine only lasted about 4 days for me before I felt like it was starting to dull and needed to be polished again with the smooth side of the block. Bit disappointing considering they advertise 10 days of shine. I did get 10 days out of using it for a pedicure, though, since socks act like protection. My photos show a before and after on both hands. I do like that they sell replacement pads, but so far the block has held up fine for me after doing a manicure and pedicure. Obviously don’t dig the tips of your nails into the buffer and it won’t become scratched up like some reviews show. You should just be gently gliding it over the surface of the nail, not digging the tips of your nails into it. Since I only plan to use this infrequently, I justified paying $13. But if you’re someone whose thick nails can stand up to more frequent buffing without taking on too much damage, I’d say go with a cheaper block from a beauty supply store and get the same result. Also, don’t fall for the “Japanese” marketing - as far as I can tell, Onsen is an American brand owned by an American man who visited Japan once and now names his products things like “onsen” and “pagoda" for the foreign appeal. ... show more

Leaves a lasting shine. It has been harder and harder to find a decent buffing block for nails but this one seems to work well.
