I as an amateur illustrator have been not so much hardship to the different attention of pencils. That's why I've bought more from curiosity that pins set and am really excited about Ihnen.So I finally cure the different self can test and the differences are really extreme. Okey back to the product itself: They are great in the hand and even with previous continuous use is so far nothing abbgebrochen neither when drawing even at peak itself. Here, the quality of Faber's really noticeable! All degrees of hardness are as described here and the metal case is perfect for transporting the pins! This pencil set worth.
