UNI - BALL VISION NEEDLEローラーボールペン 12-Count

These are by far my favorite pens in the world. They are a bit more pricey for being disposable, between $1 and $2.25 a pen based on any sales. However the price is well worth it! First - I love the needle tips. I hate cone tips, despite that being normal, because they can often create more friction and expose less of the ball. Needle tips have less friction area holding the ball in place and expose more of the ball outwards. For me, combined with the psychological desire for a needle tip as a way to improve writing accuracy, it also makes the pen glide and write more smoothly even at sharper angles. The needles themselves are relatively strong, but if you push hard enough you will bend it. But they can take a lot more pressure than I expected. The ink in these pens is also absolutely amazing. Its the Uni "Super Ink" which is pigment based, not dyes, and is far more permanent than even sharpies. It is fade, fraud, water, and solvent proof and made for Archival purposes. This is thanks to the pigments. The fraud proofing is why I always use these pens for important documents. Otherwise I just love the ink. It's water thin. It's nothing more than a "carrier fluid" made mostly of equal parts water and alcohol, plus a small amount of additives such as lubricants for the ball at the pen tip and agents to enhance other properties. The water/alcohol allows the ink to dry super fast that smudging is practically impossible. Gel pens easily take several times longer to dry, and even regular Bic cheapo ball-points smudge easier. The carrier fluid is there simply to carry the nano-particles of undissolved pigments so they penetrate into the paper and embed themselves into the paper fibers. The pigment particles cannot be dissolved - unlike dyes - which is why it's fade and fraud proof. The pens are comfortable for long writing sessions in my opinion, despite not having any kind of padded/rubber grip. I believe this is because you need nearly zero pressure to write skip and fade free with these pens. For example, to fully engage the pen in skip free writing takes almost no pressure, such that the weight of the pen itself is sometimes adequate. This allows me to grip the pen less hard, extending comfortable writing sessions. Additionally, it's incredibly comfortable when writing in cursive to be able to just lightly glide the pen across the paper. Since I write exclusively in cursive, I find it possible to write for hours at a time, just gliding the pen along the paper. The 0.5mm pens write a pretty fine line, however the ink being so thin expands a tiny bit it really writes more like a 0.6mm pen, so I never use anything other than 0.5mm and wish they made it at 0.38mm too! It's a comfortable pen, with an awesome and unique ink, with a greate needle tip that writes super smooth for the class of pen it is, and lays down a wonderful line as you write. It's absolutely an amazing pen. The only downside to such a pen is that the ink runs out much faster than Bic cheapos and still a good bit faster than gel pens. If you write in cursive, you're using 2x to 3x the ink for the same word, so that'll kill your ink fast. So be mindful that your ink will run out faster, but the transparent tank does help make it easy to monitor and they do provide a considerable amount to start with honestly. Overall these have been my favorites since 2015! Please don't stop making them unless it's just an upgrade or redesign. I want needle tip!

Muito boa a caneta. Produto de primeira. Achei que a tinta é muito forte, achava que era um pouco mais fraca. Parece caneta em gel e não esferográfica.

My daughter loves it
