It leaves a strange shine on the skin afterward. I suspect it may lead to thickening of the skin with repeated use.

Instead of glued emery paper or rough metal teeth, the surface of the glass is etched with laser beams at a microscopic level (micro-dots):

Hundreds of tiny, uniform protrusions with smooth edges are created.

These protrusions are so small that they can only “catch” and file away the dead, hard skin cells (the stratum corneum), leaving the healthy and elastic skin completely untouched.

Because of this non-porous glass construction, the dead cells do not penetrate the material. A simple rinse with water under the tap cleans it 100%, making it the most hygienic and durable choice for home care.

THERE IS NO WAY!!!
for a man’s cracked foot due to summer when I happened to deal with it, I was rubbing away with the emery papers and nothing was getting done! with the dr. scholl's file in 2 uses it became like a baby’s! Bought together with the Scholl cream for cracked heels!
YOU WON’T BELIEVE THE RESULT!!!

The best money I have ever spent! The product is simply perfect! It removes hard skin from the very first use, it is unique! The result is smooth and soft! Incredible product!

10 stars, the result is amazing!!! On dry, clean skin, with no effort at all due to the ergonomic shape, it removed just as much as needed and my feet are softer than ever! With the first use!! (for moderately dry skin, without cracks - in such cases I believe treatment is needed first).

I have tried so many files, never one this good. I don't know how long it will last, but I am willing to buy it as long as it exists!

I think once a week is good, plus moisturizing cream daily on the feet. And use gentle movements, so as not to irritate the skin.

Incredible product, I had tried everything and I didn't believe I would find something that would leave my heels like a baby's, I was shocked when I used it for the first time, I got it for my mom too and she was thrilled as well

Amazing! I used to use the old one from Scholl which was a pumice stone that was discontinued. I bought this one because of the good reviews and it really works, I didn't expect it to be this good. Expensive but worth the money. I have used it 3 times, so I don't know how quickly it wears out.

It is a very nice product. So far I haven't tried anything better. It made my heels velvety.

I read the reviews and bought it, guys it's unbelievable!!!!! It does an amazing job, I've never felt my feet so soft. Incredible product

Easy to handle, works better on a dry foot, smooths it a lot! If you have cracks, you need cream afterwards.

Be careful not to overdo the rubbing because you might get burned without realizing it.

In general, I highly recommend it, it's perhaps the best I've used, and made of material that hasn't rusted (so far) from water, etc

While with all the scrapers I have bought in my life I have dealt with dry heels, I could never remove the hard layers of dead skin that were there even if they weren't visible. They drove me crazy and wouldn't go away no matter what, only with those razors that aren't for me. Finally, I bought an expensive glass foot file, but it didn't have a cover like this one and I found this one later unfortunately, MUCH CHEAPER (the other one without a cover cost €20, while this one barely costs €10). There is no comparison, it made my heels and the area under my toes soft like the sole, I have never felt this on my feet before, finally after so many attempts, the only foot file in the nearby market that worked for me.
