Kokuyo adds a simple twist to a highlighter pen allowing you to highlight, circle, or outline any text!

Several years ago I slammed my highlighter into a corner and left 2 jagged edges leaving vampire like tips (I might have also just carved a triangle out with an exacto blade late into a creative night procrastinating). Anyhow, I used the pen until it dried up, but I never thought I’d see this accident turn into a product! Accidents(procrastinating) are sometimes the best inventions!
