With this box of 60 colors, was an excellent compromise just 20 euros more than the box of 36 and still far from the 150 euros it costs the big box (curiously). The rods fit into the usual box green bottle of the brand. Due to last years and serve. Convenient, is not larger than the size 36 but higher with two plastic trays not very stiff but with holes to lift with your fingers without bending (on two floors). There is a small booklet with a color chart that I always practice to preserve. Indeed, a great asset of this brand is the replenishment unit: we find these pencil unity everywhere and can therefore buy only those that were worn faster and there suddenly the first investment makes sense.
The rods themselves are round, very well finished. Resistant to water, these pencils are neither estompables or watercolor. The mine is 3.8 mm and width allows two sizes according to the custom of each. The pink cedar wood allows a size knife or cutter very easy. The color was easy to apply and allows for nuances. They each have a color name in German and French as well as the reference number for the easily found. Attention to colors indicated by the color of each pencil is often slightly darker on arrival. So we'll know them well.
Really buy these pens is a real gift for drawing that is with good material. An investment in the time for this kit that offers the best compromise between price and choice of colors.
