Pentel Orenz Nero Mechanical Pencil

Pentel’s Orenz Nero is a technical marvel and one of the coolest mechanical pencils sold today. It is an auto-advancing, anti-breaking pencil with a super cool aesthetic and great build quality. Despite all this, the Orenz Nero does have some issues that are worth knowing about before you invest in one.

Another interesting quirk of the Orenz Nero is that it’s not made of metal, despite feeling like it is. Pentel says it’s made of a “plastic metal blend” which seems to have some of the warmth of plastic but more of the weight of metal. Functionally the material works quite well, but it’s a bit confusing when you use the pencil since you can never quite tell what you are holding.

The Orenz anti-breaking lead technology allows for super slim 0.2 mm and 0.3 mm lead diameters. This is possible because the lead is never designed to extent more than the barest fraction past the lead sleeve (aka the pipe). This system looks odd — it looks like no lead is extended — but works rather well. The only problem with this is that the pipe can sometimes contact the page which is not a good writing experience and can even damage the paper.

The naming of the pencil is amusing but overthought: not only is the pencil all black (black being “nero” in Italian) but Nero is Orenz spelled backwards without the “z.” Pentel typically prints the name as “orenznero” to make the palindrome as obvious as possible.

The lead advance system is different than that of the standard Pentel Orenz, which requires pushing when you need more. With the Nero you only push the top button to extend the pipe or retract it, the lead advance itself as you lift the tip and push it back down between letters.

Pentel Orenz Nero Review

There is a lot of love here but despite all the technology this is not a great writing pencil. It lacks the lead-spinning technology of something like the Kuru Toga so the lead can get rather sharp at the tip. When coupling this would a skinny lead, you can have a very scratchy writing experience, especially with the 0.2 mm model. I’d recommend getting the 0.3 mm model if you do want an Orenz Nero.
