One of my favorite papers has been the stuff in Kokuyo Campus notebooks (both grades, 30 pages). Perfect size, and I've been happily using it for years. One day, a Wing Sung 601 filled with Quink Blue started dragging on the page of a new notebook, the ink coming out pale and stingy. I flushed the pen. No difference.

It wasn't the pen.

Several other pen-ink combos exhibited the same problems: stingy ink flow. I have been using that (and other KC) notebooks with pencil for things like shopping and to-do lists. But I have also recently noticed similar problems with some Clairefontaine and Rhodia papers! As though the coating itself was somehow clogging the tines of the pen.

Anyone else have this problem?

Did anything help?
