Great lead
It's somewhat smear resistant fro the oils in your hand and the dreaded graphite dirty paper when stored. but it does smear under highlighters. I use it still because i rather it smear under highlighters (the pastel sharpie ones) than get a whole notebook ugly and dirty with graphite smears. It's over pretty great quality. The lead case can be pretty discerning or confusing when its time to first open it. it's a slide out compartment! You can write relatively fast with this without breaking. The weight of the lead is true to form and is dark as it needs to be. It comes out and holds edge for a long time before needing to be lengthened. So I wouldn't say its particularly sharp, but its also not overtly blunt and hard to write with.

Reliable pencil leads for school use
The Uni 0.5mm HB leads write smoothly without breaking easily. Smudge resistance is good, making notes cleaner. A 5-pack with 40 leads each is plenty for school or office use. Verdict: High-quality, long-lasting leads—great value for students.

One of the best leads out there
Great lead. Lead is high quality and does not smudge as much as other leads. They are very light weight. The color (graphite grade) is HB which is perfect for every day use. The writing speed is great as it is high quality it glides easily.

From Freshman to Senior Year - Best Lead I've Ever Purchased!!
You can tell that everything about this product is well designed. For me, these sticks are long-lasting and moderately durable. I've used this lead since freshman year, and now I'm graduating with it as a senior. IMO, the best thing about this lead is it's smear-resistance: as a lefty, lead has been the bane of my existence. But with this lead, you can literally highlight over your writing!! Some days your hand may still smudge or your highlighter doesn't go over cleanly, but whenever I forget to carry this lead, I can immediately tell the difference between this and standard lead. Each of these packs lasted practically an entire school year, and all things considered, buying this premium lead is a drop in the bucket for all the small conveniences it provides. Please consider supporting this stationery company!!

Ok quality, decent smudge-resistant lead
I bought the Uni smudge-proof lead to go with my new Kuro Toga advance pencil. I was tired of highlighting over my notes and it smearing my writing. I did a quality test against Bic 0.9 pencil lead and the smudge test is pretty obvious on which one did better. Though, it could also be because there is less lead on the paper since it’s 0.5mm vs. 0.9mm (I didn’t have another 0.5 on me at the time). The highlighting on the 0.9 was obviously worse than the 0.5. So far, the lead is proving pretty decent quality and it’s not cutting into the paper. I’d buy it again. Update: I tested against Uni 0.5 regular lead and the tests were pretty similar, but the smudge-proof did smudge a little less, so 4 stars it is. It’s personal preference at this point on whether the smudge proof or standard lead is the better lead.

Lead Review ❤️
Lead is nice. Very comfortable,doesn't break as my previous .5 lead. Very good value considering you pay 10$ ish. It's a very good functional lead the smear resistance is nice I reccomend to use it with uni kuru toga pencils. Overall 9.5/10

Huge Difference for Smudge Control!
Total game changer! When I draw, my hand always rests on the paper, which usually smears the whole page with pencil dust, making lines fade and look messy overall. These Uni leads aren’t completely smudge-proof, but they make a huge difference compared to the regular lead I used before. Check out my photo.. the two top scribbles are with the Uni lead, and the two bottom are with my old pencil lead. I rubbed both sets equally, and the Uni lead hardly smudged, and the lines remained crisp, meanwhile the bottom smudged immediately and lines began to fade away... Definitely worth it if you draw like me and you want less smudging and cleaner art!
