More Info : QuickDraw
The QuickDraw is a 25′ tape measure with self-marking feature for quick and easy layout work. It uses a steel roller wheel to transfer graphite pencil marks to your workpiece.
Each graphite cartridge can be used to make up to 1000 pencil marks, and refills are available. The cartridges look to be 0.9mm pencil lead refills, and so you might be able to buy them separately.

The company says they’re “4D” graphite refills, but you can probably get away with HB refills or whatever you can find for cheap.(toolguyd.com)
