Here we have a complete set of glow in the dark Retro 51 pens. That would be thirty-nine over the counter and one prototype pen. The last one was the 2019 Tokyo Skyline. The first one looks like it is the 2009 Dream Catcher.
Here they are with the black light hitting them. Standing over them you get hit with real bright glow. lets hope Retro 51 continues to make glow in the dark pens. In the meantime add all these pens to your collection.
