Uni Japan, Uni Mechanical Pencil Core Lead Refill Smudge-Proof 0.5 2B Sliding Case UL-S-0.5-402B 3 Packs 120pcs With Kanji LOVE Sticker

I've been using these Uni 0.5mm 2B lead refills in my mechanical pencils, and they've been excellent for both writing and sketching. The lead writes smoothly with a rich, dark line that makes notes easy to read without requiring much pressure. What stands out most is the durability and smudge resistance. Even though 2B lead is typically softer, these refills hold up well and don't break as easily as some other brands I've tried. The writing experience feels consistent from start to finish, with minimal skipping or uneven marks. The sliding case is convenient and easy to carry in a pencil pouch or backpack, and having three packs provides plenty of refills for long-term use. The included Kanji LOVE sticker is a fun little bonus. Overall, this is a high-quality lead refill set that delivers reliable performance for students, professionals, and anyone who enjoys writing with mechanical pencils.

The best lead ever, hands down. Just like the lancer EVO(also mitsubishi) these leads are smooth and break resistant. Not only that but the case is so cool with how it opens and a very nice fidget

I have been using this lead for a few years now and it has gotten me through multiple exams and I used to buy it from other websites but it’s great that it is available on Amazon. It’s much cheaper here and the lead is smooth and is nice and dark so it is legible and good for exams and homework.

These are really strong leads. The 2B color is a bit lighter than another brands 2B (it's closer to an HB shade), but this one smudges so much less, almost to the point where it doesn't smudge at all. I had to really work at it to get it to smudge. I am using these in a new Kuru Toga pencil I just got and while I am having issues with the pencil ( I am left handed and the lead rotation is for right handers). the leads themselves are really nice and I would buy them again.

Great smoothness and no smearing! Overall awesome!

Writes smoothly and doesn't break when I give my mechanical pencil two clicks. Some people complain about durability but that's because of the amount of lead they click out of their pencils. No smudges, writes dark and has plenty to last.

10/10 pencil lead. Kinda expensive tho

Buttery smooth writing with excellent contrast

Perfect lead. Have not found anything better
