Knock Gel Ink Extra Fine Ballpoint Pen, Juice Up 04, 10 Color Assorted (LJP200S4-10C)

This is my go to pen hands down! This pen is slim in the hand with an almost pencil like feel to it. It dries quickly and writes smoothly without that ink blot/bleed you get from a .5 or .7 gel pen. I tend to write in all caps so this pen compliments straight lines very in my opinion. Overall functionality is great, comfortable grip, clicky with a sleek look and feel. My only “complaint” would be I wish they had a darker green color, similar to the shade of navy blue they have. The color variety over all is nice though.

I love these pens. They're comfortable to hold for long periods of writing. If you have tremors they are a bit too skinny for steady writing. They write very smoothly and the colors are vibrant.

These blew my 0.4 Sakura ballsign knock pens right out of the water. -No useless yellow pen -Brown and blue-black make good alternatives to black, good for when one runs out. -Refills can be purchased in at least 3 tip sizes. -Clicking mechanism is less resistant and less fatiguing over long term than Sakura Ballsign Knock and regular Pilot Juice -The design of the tip is the precision of needlepoint without the fragility. It is excellent. Good job Pilot. -Outward design is good enough for more professional settings. It doesn't look stupid or childish. -Comfortable, wider grip is good for more secure gripping with less effort, and less fatiguing compared to Sakura Ballsign, and Sakura gelly Roll -Precise tip is good for even the worst of papers, and detailed math notes -It is expensive compared to other gel pens, but worth it for 0.4 gel pens that ACTUALLY WORK -Seriously Pilot, you've outdone yourself again. CON: People will try to steal. Do not let anyone borrow them.

Typically using the Pentel gel series, but these ones are just as good with a great variety of colors. Originally looked for 0.5mm but the 0.4 isn't too far off and it's not feeling stretchy on contact which is what worried me. Highly recommend them to stationary geeks

I have been a V5 fan for years, greedily hoarding them. However, these are my new favorites. My handwriting instantly improved. The inks are vivid too.

To me, these pens are much better than the G2. They have a thin nib but are not scratchy at all. They glide across the paper smoothly and are rather vibrant than some other gel pens I have tried. There are no bleed through at all. I have no smear with them in my Hobonichi tomoe river paper. They are comfortable with long time writings.

These are great pens! I absolutely love the 0.4 tips. The colors are vibrant. The lighter colors are harder to see on yellow paper but look fine on white. Even though these are a bit more expensive than other pens, they are great. They do not dry super fast but just fast enough not to smear. I HIGHLY recommend these for any stationary enthusiast

these pens are incredibly, very precise, very smooth. ink doesnt run at all. literalyl perfect for writing. the only reason i give it 4 stars and not 5 is the casing/grip is terrible. it feels very cheap in your hand, and not comfortable to hold. if pilot put these ink cartridges into the Precise V5 rt casing, it would be the perfect pen hands down

Pilot pens are excellent. Delivery was made on time Am happy with the product.

とても書きやすくてびっくりしました。過去に0.3は使った事があったのですが細すぎて心許なく文字もうまく書けませんでしたが0.4はとても使いやすかったです。インクの色も全てとても美しいです。発色の良さ、インクの出の良さ、ペンの太さ、デザイン、カラバリ、全てにおいて完璧だと思います。特にピンク・水色・緑が大好きです。

Nice colour selection. Smooth writing and fine tip. Doesn't bleed through 120gsm paper. Definitely making the cut into my regular use pens!

My absolute favorite pens

I've used all Japanese brands and so far this one is the best of all! The glide is super smooth. The ink is highly pigmented and doesn't leave any smudges. It hasn't disappointed me in any situations. I just wish they would come in bigger versions, 0.7mm to be specific.
