About this item
- The Kuru Toga Series From Uni-Ball Mitsubishi Has A Core Rotation Mechanism That Can Automatically Rotate The Pencil Lead As You Write. The Lead Is Twisted Through A Spring-Loaded Clutch, It Works By Twisting Incrementally Every Time You Lift The Pencil Up (I.E. During Printing Words, Etc.). This Allows A Uniform Wearing Of The Pencil Lead So That It Always Remains As A Pointed Tip. So You Can Easily Avoid The Usual Problem Of Using Pencils
- At First The Pencil Has A Sharp Point, But After That When You Continue To Write The Point Is Worn Down, And Your Line Widths Are Smudgy And Thicker. Sometimes The Tip Of The Angled Point Can Scratch Or Catch On The Paper. The Lead Is Easy To Break Due To Some Positions Of The Tip And The Angles Of The Tip
- But Using Kuru Toga Pencil, You Will Not Have To Face The Above Problems. You Are Effectively Using Only 50% Of The Lead Area That You Were Previously Using With Your Old Mechanical Pencil. Thus, A 0.3/0.5 Mm Kuru Toga Will Write Incredibly Thin Lines And Have Less Breakage Than A Standard 0.3/0.5 Mm Mechanical Pencil

As a pencil enthusiast who values precision and innovation, this mechanical pencil has exceeded all my expectations.
Right from the first use, the Kurutoga Roulette Model impressed me with its unique and ingenious mechanism. The self-sharpening feature is an absolute game-changer. The pencil's rotation as I write ensures a consistently sharp point, leading to clean and precise lines without the need for constant manual sharpening. This innovation is both efficient and satisfying.
The 0.5 mm lead size is perfect for those who seek precision and fine detailing. Whether I'm jotting down notes, sketching intricate designs, or working on technical drawings, the Kurutoga Roulette consistently delivers impeccable results. The lead advances smoothly, and the lines remain consistent in thickness throughout.
The silver design exudes a sense of elegance and sophistication. The pencil feels comfortable in the hand, with a weight that strikes a perfect balance between sturdy construction and effortless writing. The build quality is outstanding, reflecting uni's commitment to excellence.
The mechanical mechanism of the Kurutoga Roulette Model is reliable and durable. I've experienced minimal instances of lead breakage, thanks to its thoughtful engineering. The retractable tip also adds to its portability and convenience.
In conclusion, the uni Mechanical Pencil Kurutoga Roulette Model in Silver is a five-star writing instrument that has won my heart with its precision, innovation, and elegant design.

- Reviewed in Canada on July 20, 2025Verified PurchaseFeels decently heavy and well constructed, allowing for an effortless writing experience. I like that I don¡¯t have to put as much pressure into writing like I have to with lighter plastic mechanical pencils. The rotating led is cool as it gives me a consistent led sharpness, but I didn¡¯t find it to be extremely useful especially considering how thin 0.5mm is anyways. Only thing I¡¯m not fully satisfied with is how thin the pencil is. My hands are on the smaller side and it sometimes gets a bit tiring to grip after writing for a long period of time. I¡¯d probably use this for jotting down quick notes on the go, but wouldn¡¯t reach for it when taking longer notes during lectures/studying.
- Reviewed in Canada on April 7, 2019Verified PurchaseNice feel to it, love the metal grip. Just below the metal grip is a rubber o-ring for a little extra help in the grip department. The top half is plastic and the bottom half is metal, gives a nice weight to it with a lower center of gravity. The Kuru Toga feature, which rotates the lead about 20 degrees every time you lift your pencil off the page, works well. Tried it on different writing angles and seemed to work perfectly. Note that the feature does have about 1mm of spring to the lead, although I barely noticed it while using. The eraser is smaller than most other pencils I've used. Under the eraser is a smaller hole than usual to insert your leads but if you turn the pencil upside down without the eraser it keeps the leads inside still unless you shake it some. Packaging is good, protects the pencil well during shipping. Included 2 leads.

- Reviewed in Canada on November 18, 2021Verified PurchaseThe worst thing about this pencil is I have to for myself to ditch the old habit of rotating the pencil myself to get a new edge when writing. I try to keep my thumb on the little circular window and it helps. I only wish it had a bigger eraser on it but it gives me an excuse to buy a cool mechanical eraser to match the pencil. It's perfect for taking notes and drawing sketches, the drafting tip works really well with a ruler to the ultimate precision line. Knurled grip feels excellent in my fingers, the knurling isn't as sharp as say in a F701, a bit smoother and I prefer it that way.
- Reviewed in Canada on January 2, 2016Verified PurchaseLove these pencils!
They're mostly made of metal, and have a nice weight and heft to them¡ªthey're not tiring to write with, but on the contrary feel a lot more stable than lightweight pencils. Of course, a mostly-metal construction means it'll be a lot more durable, and indeed, these have survived over a year of lectures and exams without much damage (mostly to the plastic bits).
The body is slightly thinner than I like for gripping, but it hasn't been too much of a problem for me. I imagine if you grip the pen too hard, your fingers will cramp up faster than with a thicker pen.
Now, the main point: the automatic lead rotation. I used to have a habit of rotating the pencil in my fingers until I found the pointed side, so it was awkward to use this pencil at first, since my fingers were fighting with the rotation mechanism. Once I trained myself not to do that, I realised that it was a _lot_ nicer to use without having to constantly rotate the pencil every word. They pencil strokes aren't super-thin hairlines like if you always look for the point, but they're definitely manageable¡ªnice and dark, not too thick.
Mostly using the Kuru Toga-branded leads for these; I haven't tried commodity leads.

5.0 out of 5 stars Best mechanical pencil ever
Verified PurchaseIt¡¯s such a great pencil and writes so smoothly that I sometimes forget that it¡¯s a pencil.
The rotating mechanism inside ensures that it always stays in shape and never feels scratchy on any paper I have tried it on. Bought it for my daily planner, but now I use it in Murdle as it¡¯s really easy to erase.
It feels really comfortable to hold as you¡¯re writing or drawing. Works perfectly well with my mini aluminium ruler.

From the moment I held it, I was impressed by its (high-quality build material). The pencil feels sturdy and durable, yet lightweight enough to use for extended periods without any discomfort. The sleek, matte finish gives it a premium look that stands out in my stationery collection.
The (comfort while writing) is unparalleled. The ergonomic grip is soft and provides just the right amount of cushion, making it easy to write for hours without any hand fatigue. Whether I'm jotting down notes, sketching, or working on detailed diagrams, the Kuru Toga feels like an extension of my hand.
What truly sets this pencil apart is its (aesthetic, visual, and stylish elegance). The design is minimalist yet sophisticated, with a modern touch that makes it a joy to use. It¡¯s not just a pencil; it¡¯s a statement piece that adds a touch of class to my desk.
But the real game-changer is the (Kuru Toga engine) (rotating lead mechanism). This innovative feature ensures that the lead rotates slightly with every stroke, keeping the tip sharp and consistent. No more flat spots or uneven lines! It¡¯s especially useful for precise writing or drafting, and I¡¯ve noticed a significant improvement in the clarity and neatness of my work.
Overall, the Kuru Toga 0.5 Pencil is a masterpiece of engineering and design. It¡¯s stylish, comfortable, and functional¡ªeverything I could ask for in a writing tool. If you¡¯re looking for a pencil that combines elegance with cutting-edge technology, this is the one. Highly recommended!

2. **Hochwertiges Silbergeh?use**: Die Premium Edition zeichnet sich durch ein elegantes, hochwertiges Metallgeh?use in Silber aus, das nicht nur optisch ansprechend ist, sondern auch f¨¹r Stabilit?t und ein angenehmes Schreibgef¨¹hl sorgt. Das robuste Geh?use liegt gut in der Hand und bietet eine angenehme Balance, was den Stift ideal f¨¹r l?ngere Schreib- oder Zeichensessions macht.
3. **Einstellbare Minenh?rte und Benutzerfreundlichkeit**: Der Kuru Toga kann mit verschiedenen Minenh?rten (z. B. HB, B, H) verwendet werden, was ihn vielseitig und anpassungsf?hig f¨¹r unterschiedliche Schreibbed¨¹rfnisse macht. Er ist f¨¹r pr?zises Arbeiten ausgelegt, egal ob f¨¹r Notizen, technische Zeichnungen oder Skizzen.
### Fazit:
Der **uni-ball Kuru Toga High Grade Premium Edition** bietet ein hervorragendes Schreibgef¨¹hl und eignet sich besonders f¨¹r detailverliebte Nutzer, die Wert auf ein gleichm??iges Schriftbild legen. Das elegante Design und die durchdachte Funktionalit?t machen ihn zu einer gro?artigen Wahl f¨¹r alle, die einen professionellen und langlebigen Druckbleistift suchen.

Verified PurchaseEl paquete lleg¨® en la fecha programada y sin da?os durante el transporte. Es tal como los describe el vendedor. En general supera las expectativas, aunque tiene un ligero movimiento en la punta al apoyarse sobre el papel que en alg¨²n momento lo hace sentir inestable y por tanto, menos confiable para lograr una escritura fluida. Cuesti¨®n de acostumbrarse, tal vez.
