Recently I had a pen(Papermate liquid Expresso) that started to dry up on me. Which meant it was the perfect time to draw with it. Here's two results before it completely died. But it got me thinking, Why isn't there a pen where I can controll the flow of ink? Or is there such a thing. I'd really like to buy a pen with low flow ink so it's not splotching and creating super thick dark lines every time. If you have any suggestions I'd love to know.
