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.

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!

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.

Great benefits from little windows... it's so smooth~~ :)

i think the little window is nice.
the best part is that it is very smooth!
