I hesitated long to invest that much for felts. I had far wingtips 68 which suited me except that it happened that colors cross, which some scratch paper and pens that different markers are seen shots. Since I tried felts Faber Castell Brush is a real pleasure to color: More colors that cross over and above traces of coloring. The tip literally slides on the sheet. However, it must go very slowly to define the contours of a precision square. I do not advise this for young children because they tend to rely too. Small flat on the delivery date that has not been fully respected but Amazon apologized and, as the box was "flattened" at the corners which could be annoying if it were ' a gift. The system of "unfolding" and "folding" is not very developed because systematically felts are no longer aligned but the principal is the good pleasure for me to make use of these markers.
