JamaasMine just arrived. Writes very light. I usually scribble on colour paper, light blue currently. I found it so light I can barely see it. Still fairly light on white. For me it'll sit on my desk at work, maybe draw some cats.
My partner just started at the same company as me. She can now see my desk setup with a tops, fountain pens, knives, lighters, headphones, and now a Cuban pen. ALL from Massdrop. I think I'll be in trouble tonight.
