Pilot Japan Frixion Ball Knock Zone Midnight Navy 0.5mm Black Ink LFBKZ-50EF-MNV Japan Import With Original Stylus Ballpoint Touch Pen

This is my favorite everyday pen for work, home, and on the go. I have three already, and I'm going to purchase more, just in case they ever get discontinued. This pen writes like butter, and the ink is bold and erases cleanly. Six stars from me!

Wonderful pen.

Bought my first frixion ball point pen when I went to Japan. I love the clip that clicks compared to your traditional top click. This one also has an eraser which I love and increases functionality. The quality is also very good and not cheap. The size of the lines it writes is perfect, not to thick and not to thin. I also like how it allows me to write fast but neat. The ink doesn't smudge either which I love. I'd definitely would buy this again.

I do like frixion pens in general but I especially like this one for the darker ink it comes with and it just write so nice

A Japanese ink breakthrough after years and years of work, in a very nice pen. The ink erases by the friction (hence the pen name Frixion) of the little polymer nub on the top. It writes nice and smooth, black ink is very black, erases fully when you want to erase. To be honest, you can get it for a lot less from the one place in the US that has them, but without Prime free shipping.

The media could not be loaded. The pen is nice, if you like really fine point and dont push hard you will like it. If your like me, where I like medium point pens mainly and I notice I do write hard (video), then this pen is not for you. Not my type.

Pilot thinks this pen deserves a metal-barrel frixion cartridge (included). I'm surprised it's not a synergy-tip cartridge, given the price of the pen, but the included cartridge is certainly a high-quality one.Still, my favorite feature is the translucent barrel, because it enables me to discern the color of the cartridge within — a benefit that is *not* on display with its default metal (opaque) cartridge!Since I do use multiple colored inks, I could see making repeat purchases of this pen, just to have the ability to run any combo of ink colors without having to guess or memorize which color is in which pen.(The barrel is not entirely transparent, so it's not as helpful as the specialty "clear 0.38 slim" frixion barrels, which can be held up to the light to see whether the ink is actually depleted. But I've found that the 038 slim cartridges really don't last long. And although frixion makes 20 colors of 038 ink, the point is too fine for some purposes, refills are expensive, and I'm not aware of any decent off-brand refills.)For this pen, you can get compatible frixion refills in a few basic colors (some with synergy tips), and you can also find much cheaper refills in bulk -- for example by Vanstek. Vanstek refills come in a much wider palette of colors than frixion offers (for this size), and are surprisingly comparable in quality for writing on regular paper. However, the Vanstek refills don't do as well on rocketbook-style smooth surfaces, as shown in photo.
