The Paper Mate Liquid Expresso is a felt tip pen with very smooth writing that keeps up with fast writers, not with thinning ink in fast strokes like a lot of other felt tips.

While Paper Mate may have overdone the flash of the design, one thing they got right was a good see-through area to let you know how much ink is left. The Liquid Expresso has an extra fine point, which seems to lay down a fairly consistent .5 mm line with quick drying ink that does a good job of not bleeding through paper.
