Review: No negative aspects, positively perfect. - A 0.5mm needle point tip makes for a superior writing instrument: very dark black ink that dries nearly instantly, fluid ink flow which enables smooth writing, even on 20lb printer paper; it also writes on thermal printer paper without skipping, blotching or smearing. The ink is fraud proof, therefore, suitable for document signing. An unexpected attribute of the pen is, if accidentally left in your shirt pocket, placed in the washing machine, and it undergoes an entire cycle of washing, rinsing and spinning, in my case, the pen did not leak ink, nor did it suffer any perceivable damage. I simply disassembled the pen, removed any trapped water, and it performed as perfectly as before the mishap. Outstanding pen in my arsenal. It may be used for drawing purposes equally well.
Review: Just about the ideal pen, especially on cheaper paper like notebooks and legal pads - I don't know what Pentel did with this pen, but it's by far the best everyday-use ink I've ever seen in a pen this cheap. This is the pen that will dry faster than all the others, lay darker lines than all the others, and never, ever bleed on even the roughest paper. I take a lot of notes at work and at home, usually on cheap legal pads from Costco, and this has the best price-performance ratio of any pen I've used. I bought these alongside the uni-ball Vision Rollerball Pens, Micro Point (0.5mm), Black, 4 Count and the Pilot Precise V5 RT Retractable Rolling Ball Pens, Extra Fine Point, 3-Pack, Black Ink (26052) , all in black 0.5mm. I tested them all together and even asked friends and family to test which they liked more - everyone confidently decided that these were the best despite being the cheapest of the three. They write smooth, don't bleed, and dry fast. Not only that, but the lines are confidently darker than the uni-ball Vision and on par with the Precise V5 ink, but without the frequent bleeding, pooling, and slow drying that you sometimes get from liquid inks - Pilot is a particularly egregious offender here if you don't spring for expensive stationery. While the other pens will certainly perform well, especially on nicer paper... they're decidedly more expensive. I got these as an add-on item for $5, which works out to about $1.67 per pen. In addition, you can usually get refills for these pens at around $1 each if you buy in bulk. I felt a little strange for liking these so much, especially since I usually can't stand gel pens, but I reluctantly realized that these simply wrote better than every other pen I had. I can't say much about the build quality or how well the ink will protect you from something like check or signature fraud, though, so consider your options more carefully if that's what you're worried about. In a nutshell, here's my take: Pros: - Never bleeds, even on cheap paper - Dries stupid fast - Surprisingly solid, deep black ink - Flows just as well as comparable liquid ink roller-balls - Dirt cheap considering the quality Cons: - Build quality is questionable - the clip will snap off if you're too rough with it - The grip, while I have no complaints, is a bit thicker than some people with small hands may like Just go for it. If you take a lot of quick notes, are left handed, or have issues with your ink smearing because it doesn't dry fast enough, this will be the best $5 you spend all month.

## Questions & Answers

**Q: Will the problem of the cracked barrels that has been going on for over 3 years ever be addressed? I see A LOT of people are having the same problem.**
A: I've had the exact same issue. Pen had a crack just above the grip; the pen doesn't stay together. Have to keep finding the pieces after it goes flying everywhere. I've bought refills already but I won't be buying anymore after I'm done with the refills.

**Q: Are these the cheaper ones made in Mexico or the high quality ones that are made in Japan?**
A: The ones I received (May 2020) were made in Mexico. Definitely cheaply made - even the box was falling apart when I received them. One barrel was already cracked. We could attribute that to bad packaging, but my "old favorite", which was made in Japan, would NOT have cracked in shipping. I also noticed right away that the barrel color was different. 
I've used the ones made in Japan for 20+ years and they were - emphasis on were - my favorite pen.

**Q: The title/description says .5 mm needle tip, but the picture shows the larger medium tip. Which is correct?**
A: There are 3 options of tip size on the one page- .5mm .7mm and 1mm.
Not all sizes are available in all color options and not all color and size combinations are available in the multiple pack quantity options. Whichever size you choose in whichever color opted for will arrive in the pack quantity selected despite what the generic picture depicts as it is only 1 of the many options offered.

**Q: Is the ink waterproof? Can I use highlighters without smear?**
A: The ink is waterproof and you can use a highlighter - just make sure the ink is dry before highlighting.
