Uni Smudge-Proof Lead. Product features ■ Clear and dark but hard to get dirty (smudge proof manufacturing method) The core powder adheres highly to the paper surface due to the unique composition of the ingredients. You can write clear and dark letters, and it is resistant to rubbing, so you can keep your notes clean after writing. It is a mechanical pencil replacement core that is ideal for making notes that you can look back over and over again because they will not fade away. It suppresses dirt on the paper surface due to scratching between the paper surfaces and contact with hands. * About the smudge-proof manufacturing method This is a new manufacturing method for manufacturing an adhesive core that suppresses stains by adhering the core powder to the paper surface by blending unique ingredients. It is named after the English word Smudge-Proof, which means that it is resistant to rubbing and does not easily bleed. While retaining the "strong," "dark," and "smooth" features of conventional products, we have added the features of "difficult to get dirty." ■ Characters do not easily bleed even when a marker is drawn Even if you draw a marker such as a highlighter pen, the spread of the core powder is suppressed, so the characters do not bleed easily and the paper surface is not soiled. It also reduces dirt from the core powder that adheres to the marker pen tip. ■ Simple design case Adopted an opaque and matte texture that does not show the contents. The design is based on off-white, which fits into the living space regardless of the core diameter, and is a simple and timeless case. The circular indentation in the center of the case provides a visual accent, and at the same time it can be used as a finger hook when sliding to open and close the case. ■ Sliding case makes it easy to take out the core Since it can be opened and closed with a simple slide Review: Superior lead - Perfect lead. Have not found anything better Review: Smooth, Dark Writing with Excellent Smudge Resistance - 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. ## Features - [Smudge Proof Manufacturing Method] A new manufacturing method for manufacturing an adhesive core that suppresses stains by adhering the core powder to the paper surface by blending unique materials - [Core diameter] 0.5 mm [Quantity] 40 pieces x 3 pieces - [Hardness] 2B - [Size] Length 76.0 x Width 20.0 x Thickness 7.0mm / Weight 6.3g - [Material] Front case: ABS, back case: PP - Suppresses the spread of the core powder so the characters do not bleed and the paper surface stays clean. - Kanji Love Sticker Included ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09B79RCN5 | | Best Sellers Rank | 400,215 in Stationery & Office Supplies ( See Top 100 in Stationery & Office Supplies ) 748 in Mechanical Pencil Leads | | Brand | XFQUIJ | | Brand Name | XFQUIJ | | Customer Reviews | 4.7 out of 5 stars 180 Reviews | | Item Weight | 6.3 Grams | | Item weight | 6.3 Grams | | Manufacturer | Mitsubishi Uni | | Manufacturer Part Number | ULS05402B-3P | | Model Number | ULS05402B-3P | | Number of Pieces | 120 | | Number of pieces | 120 | | Point Type | Medium | | Point type | Medium | | Style | Gel | | Unit Count | 120.0 count | | Unit count | 120.0 count | ## Product Details - **Brand:** XFQUIJ - **Item weight:** 6.3 Grams - **Number of pieces:** 120 - **Point type:** Medium - **Style:** Gel ## Images ![, 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 - Image 1](https://m.media-amazon.com/images/I/51-4J169PfL.jpg) ![, 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 - Image 2](https://m.media-amazon.com/images/I/61sRp7V+AVS.jpg) ![, 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 - Image 3](https://m.media-amazon.com/images/I/41vDVWj7+wS.jpg) ![, 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 - Image 4](https://m.media-amazon.com/images/I/41J6UgBi1HS.jpg) ![, 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 - Image 5](https://m.media-amazon.com/images/I/81LozQDN4pL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Superior lead *by M***S on 20 February 2026* Perfect lead.
