I am huge into arts. When I saw these pens, I was not sure how they will work. But I thought of giving it a try. I am very impressed with these. When we write, it just writes the lettering the silver color with the outline of the color pen you choose. I used them on cards and arts. Its a great gift also, to give to nay art loving person or kids birthday parties. I am really impressed with the set. I hope it lasts a long time, so that I can make a good use of it on different projects.:-)
