Pilot, Iroshizuku, Kon-peki, Deep Cerulean Blue, 50ml

My fountain pen had become progressively more frustrating to use as it developed a very irregular flow of ink despite repeated cleaning. I thought the problem might well be old ink. Looking over the selection at Knight’s I settled on the Pilot Iroshizuku range and chose the kon-peki version of blue. This ink has revitalised my old Waterman pen giving a nice smooth, constant flow of ink from the medium nib onto the paper. Would I buy this ink again? Definitely yes, I like the nice lively colour, its not your typical sombre blue. However, this 50ml bottle will last me for some time so, more likely, I'll be trying several the other colours from the Iroshizuku range and they should brighten up the pages nicely as I write.
