Uni-ball Propus Window Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - 5 Color Set

I'm a huge stationary nerd, so as soon as I saw these highlighters on JetPens, I had to have them. The hook was their nifty window so you don't over-highlight. I'm a chronic over-highlighter-- As in, I'll go well into the next sentence if I don't think about it and stop myself-- so these seemed *amazing*. Honestly, though, the windows aren't the best feature.

The Propus Highlighters are double-sided. That means that one side is a regular (windowed) highlighter and the other side is a thin marker tip that uses the same highlighter ink. "What would I need that for," you ask? Don't worry: I thought the same thing. When I started using the Propus, though, I realized it was changing the way I read textbooks. Now, I make a thick highlight over the key point, word, or phrase with the regular highlighter side. When I get to important sub-details, I use the thin point to underline, box in, draw arrows, star, and even write notes. With this new highlighting technique, I feel much more productive and understand what I'm reading better. These highlighters are a must for students!

I really like these highlighters. The window isn't as great as I had hoped, but it's good. You have to use the highlighter at quite an angle for it to actually be worthwhile, but if I have something to highlight that needs to be done very carefully, they're great.

The thing I like most about them is the ink color. All of the pens have bright inks, and all of the colors allow the text below to be easily visible. I haven't tried to photocopy them, but they appear to be light enough that the text will show through on a copy. I've never really had luck using blue and green highlighters because they're always too dark to allow the text to be easily visible.

The other thing I like is the scent (or lack thereof). I can't smell the highlighters when I'm using them, but I think I smelled something when I brought the pen to my nose (it's very mild or it's just my imagination, I'm not sure which).

best highlighters I have ever owned.

I did not need these highlighters, because I have a lot in stock. But I still bought them because the colors looked so beautiful. In real, the look just as nice as on the picture. My experience is: Jetpens always ships fast to Europe.

The Uni-ball Propus Window is my favorite highlighter out of the whole Jetpens collection. The window is a neat design feature although it probably is not something many people would find useful. I do fund myself occasionally glancing through it to see the end of the sentence or text I am highlighting, I hate when I go over and begin the next sentence on accident. With or without the window I would not change my opinion on this product, the color intensity, ink flow, style of the duel tips, and feel on paper makes it far superior over any other highlighter I have tried and I have at least one of every highlighter Jetpens offers and many more. The orange is my favorite but I think every color is great and I especially like the soft color line. The width of the tip on the window side is awesome which is why I think the window design is great even if you never use the window. The ink rarely shows through on any type of paper I have used and the flow is so good that every stoke is uniform without any heavy spots at the beginning or end of the stroke. I would recommend this line of highlighters to anyone who asked my opinion. Hope this helps someone make a good buying decision.
