This results in consistently fine, smudge-free lines ideal for professionals and students alike. Made in Japan with a sleek black body, it offers ambidextrous use and enhanced durability, making it a top choice for precision writing and sketching. ## Description The Kurutoga has a core rotation mechanism that continually rotates the pencil lead as you write. A spring-loaded clutch twists the lead incrementally every time you lift the pencil from the paper. This allows a uniform wearing of the lead so that it always remains pointed. This is great for students! It gives you an amazingly thin line. In effect, you use only 50% of the lead area that you were previously using with your old mechanical pencil. In addition, this new Kurutoga is equipped with a pipe slide system.The lead is difficult to break as you write, due to the innovative mechanism. When the core is reduced, the pipe gets shorter at the same time. The guide pipe protects the entire length of the lead. Because there's no lead breakage, your papers remain clean without smudges from broken lead dust. Review: The BEST mechanical pencil! - The uni kuru toga pipe slide is way better than those low quality plastic ones - this one is great quality, feels great to hold. The design is beautiful, I love how the mechanism looks, the turning mechanism is really nice to write and sketch with. The pipe slide model has the W Speed engine, which means the turning mechanism is 2x the speed of the standard model, and there is a massive difference! Another pro is the 0.5mm lead - way better than 0.7 or 0.9 in my opinion, the sharp 0.5mm paired with the turning mechanism gives amazing handwring results. And it has worked with many different brands of lead. Review: SOOO GOOOD - BUY IT NOW ! The design and quality is amazing and the it really does sharpen as it says and its so nice to write with. 100% recommend it for the value , the lead it comes with is pretty soft and nice to write with aswell. ## Features - Mechanical pencil from Japanese stationary Brand uni (mitsubishi empitsu), kurutoga pipe slide model, available in 3 body Colors - Model: M54521P.24 - Kurutoga pipe slide M54521P.24 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B017BDDZ7I | | Age Range Description | Adult | | Best Sellers Rank | 33,958 in Stationery & Office Supplies ( See Top 100 in Stationery & Office Supplies ) 172 in Mechanical Pencils | | Body Shape | tubing | | Brand Name | 三菱鉛筆 | | Closure Type | Twist | | Colour | Black | | Customer Reviews | 4.5 4.5 out of 5 stars (5,859) | | Drill Point | Fine | | Global Trade Identification Number | 04902778199480 | | Grip Type | Sleeve | | Hardness | 2B | | Included Components | Pipe sliding system | | Ink Base | Oil | | Ink Colour | Black | | Is the Product Left or Right Handed? | Ambidextrous | | Item Diameter | 0.5 Millimetres | | Item Dimensions | 19.3 x 1.5 x 5.1 centimetres | | Item Weight | 10 Grams | | Line Size | 1_0_1_9mm | | Manufacturer | Uni | | Material Type | Plastic Metal | | Model Name | Kurutoga Pipe Slide | | Model Number | M54521P.24 | | Recommended Uses For Product | For taking notes at school or university | | Special Features | Continuous Lead Rotation | | Style | Sleek | | Theme | Writing Instruments | | UPC | 796487250082 300718340178 | | Unit Count | 1.0 count | | Writing Instrument Form | Mechanical Graphite Pencil | ## Product Details - **Age range (description):** Adult - **Brand:** 三菱鉛筆 - **Colour:** Black - **Ink colour:** Black - **Material:** Plastic Metal - **Model name:** Kurutoga Pipe Slide - **Point type:** Fine - **Special feature:** Continuous Lead Rotation - **Unit count:** 1.0 count - **Writing instrument form:** Mechanical Graphite Pencil ## Images ![Uni Mechanical Pencil Kurutoga Pipe Slide Model 0.5mm, Black Body (M54521P.24) - Image 1](https://m.media-amazon.com/images/I/61h9r6XaRoL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: What refills fit this pencil and can you get them from amazon** A: This pencil uses a 0.5 mm lead which can be found on amazon. **Q: What grade of lead is in the pencil ie H, HB** A: You can fit what you like as long as it is the correct size.

It's almost like using a pen but with a pencil. As you write the lead rotates and pushes out the pencil just enough to write with. I wish I'd bought one of these mechanical pencils years ago. I'll never use a standard pencil or a "normal" mech pencil to write with again. I bought it at a great price too.
