I was surprised that I quite enjoy Noodler's Blue. The colour of Noodler's Blue reminds me of Pilot Iroshizuku Kon Peki. The blue pops off the page just like Kon Peki. However, the ink has the extended dry time of Noodler's inks. Plus Noodler's inks are probably cheaper than Iroshizukiu inks. Shading is visble in a medium Japnese nibs. This is a no fuss gernal usage blue ink.
