Interesting! I will have to look for it and compare pricing to the "Blue Line Eraser" which seems very similar to that.
Blue Line claims that it will come out even after being accidentally ironed on, but I have not tried to get it out after ironing myself. It has come out of every fabric I've tried it on though. They sell a package that includes a refillable "pen" that works like the one he uses in that video you posted. So far, it is my favorite marking/removal product!
