About the quality of stable markers you have to lose no word actually. The colors are excellent, the pins blur when using not, not fluff, and they are also good in the hands of young and old. This great case includes not only the otherwise normal 24 pins in many colors six additional pins with neon colors. And just as it always did the normal color of the filter (and this time do) convincing as well as the neon colors-felting. My daughter is thrilled and now most of the images she paints are designed with these very bright neon colors. The case makes a good impression and ensured even with small painters and painters a beautiful order and no flying in the nursery pens. I highly recommend this Stabilo Fasermaler unrestricted - and my daughter too!
