## Description

Uni Mechanical Pencil Kurutoga Roulette Model, Gun Metallic, 0.5 mm (M510171P.43)

Review: Best mechanical pencil I ever owned. - Metal body feels comfortable. The rotating lead means there is no problem with a chisel edge forming. Eraser is a little small. I use a separate eraser when I am expecting a large amount of corrections.
Review: Excellent well made pencil. Great Value for money. - Excellent pencil - i use this for note taking, marking up technical drawings and sketching in the field. The pencil rotates the lead imperceptibly so that you always end up with an even stroke width when using it. Two complaints; - the eraser at the end is exceptionally small and once used it will almost certainly impede or slow down access to the lead chamber - the small covering cap is also irritatingly easy to lose. Id prefer it had no eraser in the tip and just a capping piece for the lead chamber. The topmost section of the cap is also made from plastic which is slightly lesser well made than the rest of the pencil. - the silver cap/boss at the writing end can occasionally be easy to remove while in use - not a deal breaker for me though. The tip of the pencil (where the lead exits for writing) is v sturdy and has been impacted several times by me when the pencil has been dropped - it has never broken or bent this far (touch wood). Im a klutz and this is well made for my "needs"!! I love sketching with this pencil - i know that's technically not what its for but i find the control satisfying and the point never dulls so its great for precision work. If you draw / sketch in your job this is the pencil for you! The grip is comfortable, the weight is solid and to me is well balanced. The pencil is well machined and assembled. From memory the "instructions" were mostly in Japanese and i threw them straight in the bin - i didnt need instructions for a pencil!

## Questions & Answers

**Q: Hi, is there any way of getting replacement erasers for this pencil? I realise I could buy a separate one but I would prefer one in the pencil.**
A: Hi Dominic, I've not bought them myself because I never tend to use the eraser in the pencil, but I have seen them on www.cultpens.com (brilliant site) as 'Uni Eraser refills Type C' product code UN29346 and they are £1.62 for 5 inc vat. Hope that helps - Jules

**Q: If shipped from Japan to England, is there any duty to pay on the item?**
A: UK import VAT is charged on shipments of £15 or over (including shipping and insurance), and customs duty on shipments £135 or over. So a single pencil won't trigger VAT, but if you buy more than one item at once from the same seller it might.

**Q: Is the body of the pencil metal?**
A: Unfortunately no...I would like it made from metal as well.  But it is indeed a good pencil.

**Q: I have put leads in where advised but they aren’t coming through. These are the leads which came with the pencil. Please advise ?**
A: Make sure any spent lead has been completed ejected (check the point of the pencil to see if you can locate any remaining lead and pull it out while depressing the lead push button at the top of pencil). Don't put any more than six leads in the pencil at any one time (remove the eraser, insert the leads, then reinsert the eraser and replace the top (push button) section). Click the push button advance as many times as necessary to advance the lead.
