Review: Works Great! - This product is awesome!! It works, and gives your nails an unbelievable hard-coat-super-shine!! Not sure the science of how this works... but it is witchcraft!!! I love it!! Works fantastic on natural nails, and acrylic nails. The shine NEVER fades or leaves, and doesn't really scratch. You don't have to re-do the filing process ever! I get my acrylic nails done professionally by my friend. I bring this bad jackson, instead of a doing a gel top coat. This is WAY better than a gel top coat. I gave an overall 5-stars, but I do have a couple of gripes... 1. It seems pretty flimsy... so I am really unsure how long the file will last. 2. It is $$PRICEY$$ for this tiny, flimsy thing!!! I mean way to expensive!!! If the file lasts and lasts... then it would be worth the price. I will just have to see how long it lasts!! UPDATE- JUNE 30 2020: I will stick with my original statement that it works, and makes your nails WAY shiny!!!! However, as you can see from my pics the shining side is completely flaking and falling apart. Keep in mind, it's flaking after literally 3 uses. Wow!!! I love how good it works, but would NOT purchase again!!! It's literally worthless now, because the shining side of the block is completely peeled off. It's way to expensive as well. No, just no!! UPDATE- JULY 2 2020: I contacted the company personally from their website (not through desertcart, since my return window had closed), and told them about how the buffing block was falling apart. I also sent in the pictures. They immediately offered me two options. 1. Get a full refund (even though the return window on desertcart had closed), and keep the original buffing block I paid for OR 2. Have a new buffing block sent to me free of charge, and still keep the original buffing block I paid for. I chose another buffing block. The customer service was awesome!! I bought this on 5/4/20 and could return it back through desertcart up until 6/3/20. Even being past the return date, they STILL helped me!! I appreciate that, and definitely will change my mind and order from them again.
Review: Simple Yet Effective! - Gave this to my daughter as a gift. She told me later after using it that she loved it and felt her nails were healthier after one use. She loved how they shined and mentioned not using nail polish anymore. She also liked that it was so simple and compact to use compared with many of other products she had bought and used in the past. She is very picky about things so i felt i had chosen well.

## Questions & Answers

**Q: I’m so sick of cheap buffers that fall apart after only a couple uses. Is this one quality?**
A: It's good for a few uses. I bought both the block and the refills so, as buffers go, I'm quite a bit of money into this thing. I was very happy with it for the first couple of uses. I had assumed it would outlast other cheaper buffer blocks. Nope, it doesn't. Huge disappointment. I won't be dropping any more money on this brand at this price ~ that's for sure.

**Q: What is the grit on the silver file side? Want to make sure it'll do the job. Sometimes they're too weak....**
A: Great question. 
The grit is 180 but please keep in mind this buffer is intended to use on the upper part of your nail and not as a nail file. 
Its purpose is to provide a perfect look and protection to your nail and not to shape the edge. We have a separate nail file package for that. Or you can look at our Japanese nail care kit that includes The buffer, cuticle condition
er serum, nail file and a free replacement set of pads for the buffer ( its a cool feature with our buffer)

**Q: Can you use nail polish after using the buffer?**
A: No,because the sole purpose of the buffer is to shine the nails without having to use nail polish. If you did use nail polish after using the buffer,it will more than likely cause the polish to peel/chip immediately. In order for the nail polish to adhere to the nail plate it has to be dry (us rubbing alcohol) free from oils or shine buffing.

**Q: can this be used on acrylics too?**
A: Yes, It is especially helpful after acrylic nails, but also works great to keep healthy nails strong. It smooths out ridges and splits, removes stains and provides a protective moisture barrier to help your nails heal and grow. It also improves blood circulation to the nail and leaves a beautiful, glossy shine that lasts up to 10 days!

### ⭐⭐⭐⭐⭐ The BEST nail product I've ever purchased!
*by L***A on August 9, 2025*

My nails look so healthy and beautiful. It looks like I'm wearing a shiny clear coat! And so easy in 3 steps, first use the Clarify side that evens out your nail texture, then the Boost side that smooths it out and then the Shine side that makes your nails look absolutely stunning!
