Uni-ball Propus Window Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Green

Awesome color, awesome ink, and both the window side and thin side are really handy. I always over-highlighted, but this did the trick! I use the thin side as a neon marker pen, but it's also good for highlighting tiny writing. One of the best highlighters I've ever had.

i thought that this highlighter would suck but i decided to give it a try.
i love it! it's so soft!!!

great

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.

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!
