When a regular Sharpie line is too thin, get a Sharpie King Size. When the King Size won’t do, get a Sharpie Magnum. I bought a red and a black Magnum for a card trick deck (they also come in blue). It has a chisel point, and its easy to get three line widths with it. If you’re an Amazon prime member, you can get one for $(removed)
