    • Perfect with some adjustments.
Size: 4 Count (Pack of 1) Style: KRAZY Pop Pattern: Pen
I love Pentel, and these neon inks don’t disappoint, they’re about as neon as neon gets, and the ink is creamy and smooth. There’s just one problem: the 0.5mm nibs. They’re terrible. They cause the ink to skip, they’re scratchy, they’re just awful, it’s like fingernails on a chalkboard the whole time you’re trying to write with them. I went through a lot of experimentation to figure out how to get this wonderful Solar Pop ink with a nib I liked. I finally figured one out. I also have the Milky Pop pens from Pentel which have the exact same barrel and body style as the Solar Pop except they come with a 0.8mm nib that is very smooth and reliable. When I got done with the Milky Pop sets, I pulled just the metal nibs out, cleaned them in alcohol, dried them, and then swapped them out with the 0.5mm nibs on the Solar Pop set. Guess what? It worked beautifully. I’m very pleased with the results, the ink doesn’t skip anymore, and the lines are more visible because now they’re not tiny. But the best part is how smoothly they write now, the scratchiness is now gone and these pens are now literally the most perfect neon pens I’ve ever had. Be advised that the blue and purple in this set do NOT fluoresce under a black light. But blue and purple are the hardest to get to fluoresce so I’m not really disappointed, it’s even kind of expected. The pink, orange, yellow, and green light up under a black light like the sun, though. ... show more

    • Very very sparkly!
Size: 4 Count (Pack of 1) Style: KRAZY Pop Pattern: Pen
Along with the KRAZY Pop, I also bought these Sparkle Pops. These are the most sparkly pens I have ever seen! They write bold and bright and all but leap off the paper! I am slightly disappointed with the gold because it looks more like a yellow ochre. But to make up for it, the grey-black one is a real surprise. I'm not sure whether it's dark brown, black, or dark red or a combination of them all, depending on the lighting and how you look at it - it is very interesting to say the least! The blue also has some interesting properties! These are going to be a lot of fun to write and draw with and I am very glad I bought the package of eight colors. If you are a fan of bright and shiny colors, you have to get these! ... show more

    • Versatile Milky, Pastel Gel Pens
Size: 8 Count (Pack of 1) Style: Milky Pop Pattern: Pen
Review Image by Sarah L. Sarah L.
Review Image by Sarah L. Sarah L.
These medium tip (relatively bold) milky pastel gel pens are fabulous on both white and black paper. The purple, blue, and pink are the most opaque of the 7 in this pack. They write very smoothly and rarely require a scribble to get started, unlike some other brands. The color of the ink dries down to the same color as when first applied and still wet. If you go over the same spot a few times, it will build in opaqueness. The ink also plays rather nicely over black marker and white-out (see photos), which is beneficial to know if you plan on using these to color, draw/paint, and/or write. The white color is nearly indistinguishable from the white Sakura Gelly Roll 10 (#50/31031), and the other colors in this pack are very comparable in most ways to Sakura's Moonlight pens of similar colors. These do not, however, compare to Sakura's 3D Souffle collection. With these being relatively bold pens and having such smooth, generous ink flow, the ink will be used up pretty quickly - but this is not a unique issue for pens such as these. You'll have that with any other pen with similar traits. They dry somewhat quickly, in comparison to other milky-opaque gel pens. Overall these pens are very nice. I will continue to use them for journaling AND drawing/painting/coloring. ... show more
