Newly developed, close contact core that keeps notes clean against rubbing. 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: 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 desertcart.

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. ### ⭐⭐⭐⭐⭐ Review *by M***S on 20 February 2026* Perfect lead. Have not found anything better ### ⭐⭐⭐⭐⭐ Review *by X***G on 21 October 2025* 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. ## Frequently Bought Together - 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 - Uni Pencil Lead, The Uni" Smudge-Proof Leads, 0.5mm HB, 40 Leads x 5 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/568690652-uni-mechanical-pencil-core-lead-refill-smudge-proof-0-5](https://www.desertcart.com.kw/products/568690652-uni-mechanical-pencil-core-lead-refill-smudge-proof-0-5) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-28*
