I tested these out last evening and they all worked fine. When each one is activated, you do have to press down on the tip, a half dozen times or so, before the paint begins to flow. I played around a bit, and was very happy with them. There wasnt any noticeable shift in color when dry. Do be sure any paint is dry before you go over it with another color though. Otherwise you will get the first color on the tip of the new color pen. This happened to me. I quickly released more color; dabbed at the tip with a wet paper towel, and it cleaned up fine. I would use another blending tool, if you like to blend when you paint. I am not a blender/painter, so I didnt test that out. Another thing I did test though was using it to ink up some home made stamps made of craft foam. They worked beautifully for that application. These will be great for art journaling. Because all of the information was in another language, I do not have any idea of the lightfast ratings. I would not use them in any fine art pieces. The pigment load seems good though, and as mentioned before; dry true to color.

Love them.
