## Description

Mechanical pencil from Japanese stationary Brand uni (mitsubishi empitsu), kurutoga pipe slide model

Review: An artist's pencil that keeps the lead from uneven wear-out - Though on a slightly expensive side, this is a pencil that suits an artist, architect or a writer who needs the lead to remain sharp and pointed without uneven weariness. Even single lift of the pencil from the paper, turns it a notch and keeps the lead/point sharp. The build is plastic and though looks well-built, I would not suggest it for school going children, it is more suited for adults. The package doesn't look enticing enough for its asking price. On the downside, it uses the 0.5mm lead, and it is quite tough to find good quality lead that has ample dark graphite and doesn't break easily whilst drawing/writing. I would definitely suggest the 0.7mm model, if it is available.
Review: Good, can be improved - Stopped working after few months

## Questions & Answers

**Q: What is kuru toga system**
A: There's a real problem that affects almost all mechanical pencils. As you use a regular mechanical pencil, the lead wears down on one side, forming a slanted wedge-shaped tip. Each time you put the lead to the page you end up using a different lead surface (pointy, flat, wide, thin) depending on how you hold the pencil. This can cause dramatic and unsightly variations in line thickness as you write or draw.The Kuru Toga eliminates this problem with the use of an ingenious lead 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 to create a conical tip shape that provides a fine, consistent line.

**Q: Which one is better uni roulette or pipe slide**
A: UNI 'pipe Slide' is better.
The Lead support hides back in and does not hurt when in a shirt pocket.
Roulette has more style with a part metallic body.

**Q: Does the kurutoga system work with any lead refill?**
A: Yes. Size should remain same (0.5mm)

**Q: What lead does this ship with? i ordered extra pentel 0.5mm 4b (darkest) yet they aren't as dark as the one that came with this… what b is  this lead?**
A: Mine came with a HB lead. I have shifted to @B lead since then.

### ⭐⭐⭐⭐ Good, can be improved

### ⭐⭐⭐⭐⭐ Note/sketch taking pencil
*by V***J on 27 January 2020*

Serves well for note taking purpose or to highlight/mark in your books. Artists might enjoy sketching with it too. Needs bit of pressure while writing for the mechanism to work. For darker shades and lead strength, get pentel ain stein leads or uni leads or rotring leads. Cheaper leads tend to break or write lighter. Plastic body seems bit delicate so use caution while using it. Lead sleeve has a cushioned feel like the rest of uni variants. Not good for cursive writing as lead wears down unevenly. Works well for people who don't connect their letters while writing. As it is a product of japan, it was built for their language which have multiple, seperate, clean strokes allowing the lead to rotate. Feels sharp and thin on cheap paper while making notes. It does feel better on higher gsm paper or more premium paper.
