The product is beautifully small and handy, including, where everything you need for nice defined eyebrows: a colored wax that brings eyebrows in shape and also holds throughout the day quite well in the form of a rather neutral powder to fix the wax, two small brush (a bevelled for the wax, a rather round for powder) and the smallest tweezers I've ever seen. It is easy, apply quickly and accurately, and although they may not seem at first glance, you can work really clean with tiny brushes included! The tweezers I personally, however, not quite as convenient as can hardly be so grasp hair because it is, as it is extremely small, not very flexible. But if need be, for example, on the go, they will already be somewhat useful.
For me it lasts all day, under extreme conditions, however, I have not (yet) tested it! ;-)
The color is the way - respect - not just very bright (ie fits probably best for hair color dark blond to medium brown and all those who like to wear darker brew) and is very easy to make it reddish in my opinion, but I did at the moment coincidentally fits! To ash-blond natural hair color would all but not exactly look very natural, I think.
