Good stop!
I am extremely satisfied with the Diamond Hardener, at my job as a mail carrier my hands are constantly in use. The nail polish is the 1st that lasts at least a week on the nails and I have really fast nachfettende nails. With a colored polish on it and the Diamond Hardener as a top coat still on it. Simply Top!!!!!!!!!!!!!

Simple but ingenious
A simple, clear polish that hardens the nails and gives them a beautiful shine. Perfect! This gives you an elegant appearance even without much color :)

Simply amazing!
Makes the nails really hard, so they no longer break off! Is my absolute favorite product! You apply the varnish and when it is dry, the nails are immediately insanely hard and stable!

Ideal for brittle nails
Since my nails like to split, I generally like to use a nail hardener. The Artdeco Diamond Hardener has surprised me by the fast drying time very much. Other nail hardeners dry much slower. After the application, you have the feeling that the nails are already much more stable. Also, the chipping of the nails I got with this product very well under control.

Enthusiastic ?
Finally I have found a nail hardener that really helps. Since I have acrylic on the nails at the time, he is little needed. However, he is very good if you have his acrylic or gel from the nails and you can only in a week in the nail studio, because he protects the nail immediately and strengthens.
