Well I bought this particular ink a few months ago. I've had no issues with Diamine in the past, but this ink just seems to write dry, then pool up at the oddest times. I've tried it in 2 Pelikan M205's. It makes me feel like I'm writing on plastic. It doesn't want to absorb into the paper. I know smooth paper can feel that way, but doesn't seem to with my other inks. I tried rougher paper and it just doesn't make me want to write with it. I've read good reviews on the ink so I don't know what might be happening. I don't want to give up on it just yet!
