I tested it in a few more tablets this weekend. All Noodler's black.
1. MiquelRius - small soft cover flexible notebook. Bled like crazy! Ack! Fountain pen friendly my tush.
2. Hand*Book - crazy scratchy. Yuk Yuk Yuk
3. Moleskine Sketch book. Wrote very, very thin. As an Extra Fine should. I don't have much more to say, as I hate the Mole Sketchbooks. I suppose if someone likes them, they'd be pleased with the results.
