I’m shocked how well this works. My dried out winter nails were looking dull and ridged and this product completely fixed them. No muss, no fuss, just use the sides in order ,1,2 then plain white and my nails shine like I’ve used clear nail polish. Highly recommend.

Highly recommend if you leave your nail bare like I fall into the habit of. I have long beautiful nails but just can’t keep up with the upkeep of polishing them all the time so these buffing squares are a must! They keep your nails from splitting and getting textured. I just buff away as I’m watching tv and they get such a glossy polished look once finished. It’s beautiful! And as a little treat I’ll buff my friends or moms when we are having girl movies nights and everyone loves it!

I’ve been using these Professional Nail Buffers, and I have to say, they really do the job! They smooth out imperfections and leave my nails shiny and polished, which I love. They’re the perfect size for both fingernails and toenails, and I appreciate the two extra shining pads included with each buffer. That way, I can use them longer before having to replace them. The only thing that threw me off was the product listing saying they were made in the USA, but the box clearly says they're made in Korea, the misleading label is a bit odd. What I do like about these buffers is how well the different functions work. They’ve got sides for smoothing, shining, and stimulating nail growth, and they really deliver. The two-pack is handy, too, especially because I always forget to replace mine until it’s too late. I love the shiny finish it gives my nails, especially since I never bother with polish these days. Even though the price feels a little high for two buffers, they work really well, so it’s hard to complain too much. Just wish the info was clearer upfront!

I love that this is a two pack because this allows me to have a backup on hand when the other one wears out. It’s the type of thing you don’t realize you need to replace until you’re in the middle of a manicure. I’ve just started doing my own nails at home, heck I just stopped biting my nails, and have discovered how important budding is to keep your nails looking great, make polish stick more, and removes bits of cuticles and dry skin. These buffers work well, and have ingredients to help condition the nails. They have sticky edges so you can remove it once it’s worn out, and replace if you have the replacement pads. It was kind of misleading because upon purchase I thought these were American made, but they were only developed there. Not a deal breaker, it perhaps important to clarify. I enjoy the nice shine I get on my nails and the smooth painting surface that I achieve from using these.

My wife says: I have no idea why the product listing for these Professional Nail Buffer | Made in USA | Ultimate Shine Nail Buffing Block with 3 Way Buffing Methods, Smooth & Shine After Nail File, Purse Size Manicure Tools for Optimum Nail Care - 2 Pack By Onsen state that they are made in the USA, when they are made in Korea. For beauty products and tools, being made in Korea is often a benefit, so this choice in false advertising is really confusing. That said, these are nice nail blocks for buffing and shining nails. They work well, with ridge-smoothing, growth stimulating, and shining/polish sides that have replacement ability for the shining pads. The really do buff your nails to a smooth, shiny finish - it's a pleasure to run fingertips over the smooth nail beds and admire the shininess of the nails. The price is a bit high, even for two blocks, but they work well so my main nitpick is with the weird manufacturing claim.
