Seduced by its reputation for sheen and its color, I bought a bottle at DC. Now I'm reading of issues where even a brief pause in writing with it causes the nib to dry out, hard to re-start, etc. Two questions: Is this regarded as a common problem with this ink? And, to the degree this may be true, should I limit its use to a screw-cap pen rather than a pressure-fit or magnet cap pen to better seal the nib when not in use? Thanks!
