This review is from Uni-ball Propus Window Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Pink
I bought this as part of a pink pack by Uni-ball from a japanese airport and I was surprised at how handy a window in a highlighter could be! It's really popular with my friends and I love the duo tip! Nice vibrant pink color and you finally know when to stop highlighting! Great for the OCD people who hate those break lines!

This review is from Uni-ball Propus Window Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Blue
I never knew that a highlighter could benefit from a little window, but this is the best invention. Don't you hate it when you over highlight something? Well let me tell you that with these bad boys that will NEVER happen again. Plus the added fine tip is great for mini highlighting. An overall great highlighter.

This review is from Uni-ball Propus Window Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Blue
I bought one of these recently (when I was on my huge stationary shopping spree :)) and I am quite happy with the performance. The little transparent window not only lets you know where you're highlighting, it also helps to keep the highlighter tip straight and not bendy.

A good buy!

This review is from Uni-ball Propus Window Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Pink
As strange as it might sound (?), this is a fun little highlighter! Nice to have the broad and fine tips... and that "window" is a unique concept. The color isn't too bright or dull... just right for me. Definitely getting more of these later.

This review is from Uni-ball Propus Window Soft Color Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Lavender Purple
This highlighter is amazing. The clear window allows me to see what I'm highlighting and has a great aesthetic appeal. The felt tip side is also really useful. I alternate between both sides often when highlighting/underlining/etc...

The color is perfect. It's a soft purple that makes your text stand out, not stick out. This highlighter makes my notes so much more fun to read!

This review is from Uni-ball Propus Window Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Orange
My go-to highlighter for graduate school studies. Love the variety of colors available. I didn't think much of the window when I ordered it, but it is truly a luxury when you can see what you are highlighting through the window. Absolutely fantastic!

Some highlighters don't last very long, but these withstood every test, study review, and intense reading session.

I highly recommend these highlighters.

This review is from Uni-ball Propus Window Soft Color Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Golden Yellow
Just the right shade of golden yellow; not too bright nor dull at all. Would gladly repurchase this highlighter. I'm planning on getting the five color set to try them all out!

This review is from Uni-ball Propus Window Soft Color Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Aqua Blue
Great color and quality! These highlighters are soft and pretty, as well as being easier on the eyes compared to regular brights. The window is a great help, and now I can't go back to using highlighters without the it. Tried this color and golden yellow and I love them both; I'm about to purchase their 5 color set!

This review is from Uni-ball Propus Window Soft Color Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Cherry Blossom Pink
I find myself using this everyday and I was never a fan of highlighting before. I use both ends, they glide smoothly and the window comes in handy. It is a very cute baby pink colour and I much prefer it over the fluoro highlighter colours.

I can see myself finishing this fast. Will get the entire pack when it is back in stock :)

This review is from Uni-ball Propus Window Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Yellow
This has got to be one of the best inventions ever! The window really helps you see what you're highlighting, which is very useful for someone like me who tends to over-highlight. This yellow color is like a lighter/more faded version of the typical fluorescent yellow highlighter, but I'd recommend it if you want something that stands out more than the soft yellow one.

I gave this pen to my sister, and she love it!
she is always reading documents for the university, the tone is a little light, so if you like some more "remarkable on color" this is not your pen.

This review is from 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.

This review is from Uni-ball Propus Window Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Orange
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.

Loved this color as well as the other two I ordered... You do not even realize your looking through the window, but you do realize your not staying strait on the words your intending to highlight... love these... Oh and the small tip is great for underlining or highlighting small words on powerpoint printouts when you print 6 slides on one page.

I got Blue, Pink and Orange for my bf and he loves them :) He's very conservative when it comes to using them though, he's afraid they'll run out haha. They work magnificently, he likes them because they aren't super inky and don't bleed through the page. He doesn't use the window though, he just said they look really cool.

This review is from Uni-ball Propus Window Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Yellow
I finally had to throw my pack of highlighters away recently that I bought in Japan, gosh, 7 or so years ago now that I think about it. I had used them before, but not as frequently as of late, so you can imagine what great quality if the ink never dried out! The window allows me to see what I'm highlighting so I know where to stop and it glides very smoothly. I also like that when I highlight textbooks, the ink doesn't seep through the pages.

This is a great highlighter, I love thw twip tip characteristic a lot, giving me options. The window may not help some people, however, I find it very helpful. I can always see what I'm going to highlight next and usually I highlight too much, so this has helped me. No flaws.

This review is from Uni-ball Propus Window Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Yellow
The window feature of this highlighter is outstanding, particularly when highlighting text where the line spacing is close. Good value for the money. The only downside is that the shade of yellow is not as bright as that found in some other highlighters.

This review is from Uni-ball Propus Window Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Orange
A very nice dual-ended highlighter. The positive sides are: on the paper, the highlighting color is not terribly vivid, as it may be with some highlighters so that it even hurts your eyes too look at what you've just highlighted. Nope, this one is just right.
- The "window" option does not make too much difference, though, BUT you do get used to it very quickly since it indeed does not cover the text.
- Another positive thing is that the highlighting liquid is distributed evenly, so when you highlight something on a single sheet of paper, it does not "show through" when you flip the page. On some other highlighters (purchased at a large US retailer with the Bullseye logo :P) the liquid is just splashing out when you are pressing harder than usual, so that I ended up with bright blobs on the page. In this regard, this Uni-Ball creation is just a little orange masterpiece.
