Review: Good solid pencil, has become my dailly driver. - Reallly nice pencil, it enables a smooth writing experience, and because the lead rotates writing is consistant. The build quality is what you expect with an Uni pencil, it feels well built and will last. The pencil has fast become my goto mechanical pencil, in part because the body is a little wider than most other mechanical pencils and with bigger hands it sits just right. This pencil does not come with many extra leads so be sure to pick up a set of refils. The pentel ain 0.5 B's work brilliantly with this pencil.
Review: Works well and writes nicely - Good mech pencil, comfy to use.

## Questions & Answers

**Q: Can I use any other 0.5mm lead?**
A: Yes, you should be able to use any 0.5mm lead.  I've already reloaded my pencil with spare lead I bought.

**Q: What is the difference between kurutoga advance upgrade model and kurutoga standard model?**
A: Standard Kuru Toga pencils rotate the lead once every 40 strokes, while the Kuru Toga Advance rotates the lead once every 20 strokes. The Advance's mechanism is made with metal parts for smoother, more reliable performance.

**Q: Can you see the rotation through the grip holes?**
A: No, but if you remove the tip and the external bezel, you can see the whole mechanism in a transparent plastic tube (It is really nice). Then there you can note the mechanism moving while you use it.

**Q: what kind of erasers do I need to use to refill the pencil when low?**
A: Advance models use size "S" refills

Good mech pencil, comfy to use.

### ⭐⭐⭐⭐⭐ Extremely well engineered peice of Japanese stationary
*by D***N on 11 July 2025*

This is an excellent mechanical pencil. The design and attention to detail are really nice. It's very well engineered although the feature of turning the lead is very cool it only really works if your writing with it because your constantly lifting the tip off the page and back down again while writing so it rotates a lot more. When drawing with it, especially technical drawing, it does not do it quite as much but still gives you a nice point. This is a lovely pencil though and I am very happy with it. I find the best stationary comes from Japan.
