The yellow worked great and was what I expected: dried almost immediately and couldn't be read when held up to a regular light. It glowed under the UV light. I would recommend buying ONLY the yellow pens singly.
In addition, the fine tips of the pens are not very sturdy and one pen tip was broken by my 3 year old pressing too hard on it, so these pens are probably best for experienced writers, ages 6 and up.
In direct sunlight or "North light" (lit by the sky) the red is dimly noticeable, with the blue it really depends on the surface.
Both a Florescent Blacklight and UV LED work very well to cause the markings to show up. I have my doubts about an incandescent "Blacklight" as I could not test them with one.
I may have received a bad yellow one as the point is much harder.
Edit: I now believe that the yellow hard point was intentional. Some papers (high rag content) it works quite well on.
These particular pens worked well in that the ink lit up brightly under UV light. However after using them only a short time, I've discovered that they have a little flaw. If you are not very careful when putting the cap back on the pens, the nib (tip) fibers catch in the inside structure of the pen cap and flare off to the side. This happened right away and I had to trim the fibers off the tip that were sticking out at a 90 degree angle.
The pen caps, if you look down inside them with a flashlight, have an inner ring or cylinder with a rim on it that catches the nib fibers and folds them over. You must insert the pen into the cap perfectly centered every time or you will fold nib fibers off to the side and ruin your pen tips.
I've trimmed the nib on one pen so many times, that it is just a little nub now. The problem is that once you miss align the nib the first time while putting the cap on, and damage the nib, it easily becomes damaged while you use it to write, causing further troubles with the nib.
I'll continue using these pens until they are no longer usable, but I won't buy this brand of pen again.
The seller sent me a brand new pink one free of charge and a little three color pen that you just kinda Pop apart. Like one of those mechanical pencils with the led coming out of a plastic pellet where when it runs out you just take it and put it in the back of the pencil, revealing a brand new lead. That's kinda what this is like, but they don't get worn out that badly, you just move it when you want to switch colors. ANYWAY, all of the blues and pinks work fine, the yellow is still a bit watery, and is easy to wipe off. Glows yellow for a minute or two, then turns a bluish color and can be wiped off at any point in its lifecycle. Overall I'm happy with everything because they treated me well by hooking me up for free, I'm giving them 4 stars because 4.5 isn't an option and the yellow still doesn't work. Will probably buy again if these things ever die.
