## Description

uni Smudge-Proof Leads Refill for Mechanical Pencil | 0.3mm | 2B | 25pcs

Review: Good, Dark Lines While Being Very Durable! - I write almost exclusively with .3mm lead and being so thin it is very important to get the write type of lead. I have used some 2H lead and it is so light, but stl breaks too much. This lead provides a perfectly dark line and is stronger than the harder grades over other brands while being much more legible. I do not bother with other brands or grades anymore and just use these. I highly recommend these!

### ⭐⭐⭐ Great Lead Quality, But Packaging Was Opened
*by K***E on March 24, 2026*

The 0.3mm lead writes very smoothly and performs отлично overall—honestly, no complaints about the writing quality. It’s consistent, clean, and exactly what you’d expect from a good mechanical pencil lead. However, I only gave 3 stars because the packaging I received was already opened. I also counted the leads, and there were only 17 pieces inside, which is clearly less than expected. I originally planned to return it, but for the price, it just wasn’t worth the hassle of going through the return process. Great product in terms of performance, but the condition it arrived in was disappointing.
