The pictured Oil-base pins can be very difficult to not blur and remain visible strokes, have almost crayon-character. Who wants to have smudge sepia and Rötelstifte should definitely make sure that "fetthalting" is on the pins not "oil base" or.

But to which pins it is actually here, can not be properly assessed.
It was hard to forgive star here, but I still have to give 5 stars, even if the description does not match the picture that depicted pins that I use myself, 5 stars are worth, as well as the pins of the description.
