Optimum lubrication - lose!

For me, as a right-handed, the pins fit comfortably in your hand. A full rubber coating protects against unintentional slipping. Six different colors to satisfy just about every taste, so far suited the combination especially for school-age children and their teacher / inside, correct all that crap. I, however, use orange and purple mines in everyday life rarely.

The feel of the pins is slightly thicker and better than in the very similar, but much cheaper product variant: Case 8xKS Slider XB - but probably not yet all tastebuds. The lead material used, however, is almost identical, because here can be a very short usage not deny that small ink spots emerge at the end of mine, which the handwritten / drawn result tends very quickly to smudge. In general, the color / typeface of pens is very uneven.

And what good is the best price, if the result is suffering.
