Excessive prices, but a must for enthusiasts.

For lovers of adult coloring, the Stabilo Pen 68 are a must. Already have the Stabilo Pen 88, those with the fine mine, the interest to invest in 68 Stabilo was able to complete designs with fine detail and larger while having an identical color. In addition, if one of the felts were to stop working, they are offered for sale to the unit. I am totally convinced of my purchase, yet several caveats should be noted.
I opt for the kit 50 markers in order to have all existing references to date, and I have been fortunate to benefit from a special price offers in flash. At full price, I think it is excessive for the quality. While the ink and the colors of these felts are vibrant and beautiful, it is likely to do unpleasant marks on your drawing, even if you switch back again with color. The risks of "pill" on the sheet are present.
You should know that four references are available in dual (red, dark blue, dark green, and black) since there are only 46 references. Thus, if the fluorescent colors do not interest you, I advise you to advantage the box 40 markers.
