They say "Swarovski Elements Crystal Nail Files By Mont Bleu Crystal Files Made With Tempered Bohemian Glass in The Czech Republic. Used around the best spas in the world, they are a real luxury and the surface has a life time guarantee. Totally hygienic as Crystal Nail Files do not absorb moisture or bacteria and can be sterlized or boiled if you wish. The surface of the files are acid etched on both sides, and made using a ion exchange technology. Crystal Nail Files are totally safe as they have been hardened and tempered but allow enough flexability required, the sides and ends of the glass files have been sanded by hand and are totally smooth, you can also files both ways and any nail residue you remove will have turned to dust while sealing the free edge making your nails stronger. Pointed front tip to clean under the free edge and aid cuticle removing."
On my nails: Fiddlesticks by Butter London (feat. in yesterday's post)
For years I've been using the normal big patterned squishy nail files you can pick up in places like Boots or Superdrug and I'd never given much thought to whether or not they were good for my nails, but on reading more into it, they can be damaging. The crystal nail file isn't damaging because it seals the ends of your nails to help stop peeling, which is what normal nail files don't do.
Since using this (nearly two months) I've had much less peeling on my nails, they've become stronger and they haven't broken or snapped as easily. Yes, they've still had all those things happen, but much much less. I love that it comes in a little velvet pouch too, it makes it feel really luxurious.
This is definitely something I will keep using and eventually when it's completely worn out, I'll treat myself to another one :)
If you're wondering which one I had, it's the Mont Bleu Swarovski file, you can check out their range here.
