Unlike the previous review,...
Unlike the previous review, I find that these pens are very worthwhile. The ink
is black to me; also, it is light- and waterproof, which isn't something most
pens can boast. The wide range of sizes and the colours make this one of my
favourite pens. I find that they handle precision drawing very well.
(I advise the previous user to look at rotring instruments, i.e. rapidographs.
They are not disposable, and may just be of the right kind!)
