Tombow Mono Zero 2.3mm Round Core Precise Eraser in Package

The Tombow Mono Zero Precise Eraser is a unique tool that might seem a little silly, but its really a great accessory to keep on hand.  Before we get into the review, just a quick note that this product was provided by our friends over at JetPens free of charge for this review.

Tombow Mono Zero Fine Point Eraser Tool Compared to a Standard #2 Pencil

The above picture with the #2 wood case pencil should give you a general idea about the size of the Tombow Mono Zero Fine Point Eraser Tool.  To be more precise, it measures about 5.75 inches from clip to tip with the eraser fully retracted.  The 2.3mm eraser inside measures 2 inches long.

Here is a Closer Look at the Tombow Mono Zero Eraser Tool Refill

There are a few things to note about the operation of this precise Tombow Mono Zero Eraser tool before you start to use it.  The eraser refill itself has a somewhat flexible plastic shaft stuck into the top of it to help push it out when you click on the plunger.  When you are using this precise eraser you will want to make sure that you don’t extend it too far beyond the tip of the device.  Because it is so thin, it relies on the metal that surrounds it to keep it stiff enough to erase and not break.  In order to remove and refill the eraser in the Tombow Mono Zero Eraser tool you actually pull it out through the tip.  Adding a new eraser is done by inserting it through the tip as well.  You can not remove the plunger and replace from the top like you might expect to be able to do.

If you click on the above photo you can see that the plastic shaft slips into a tiny hole punched in top of the eraser.  I wouldn’t advise frequent removal and replacement of the plastic shaft into the eraser because it might loosen up the fit and cause problems.  I did try removing and replacing it about 10 times and it didn’t seem to cause any issues.  I can’t imagine a situation where you should need to do that, so this shouldn’t be a problem.  Speaking of refills for the Tombow Mono Zero Eraser, JetPens also has some of those in stock right now.  You might want to grab an extra or two if you do a lot of pencil writing or drawing.

The Tombow Mono Zero Eraser Tool Looks Cool, but What’s it Good For?

The Tombow Mono Zero Precise Eraser Sample

Before we get into what you SHOULD use the Tombow Mono Zero Eraser for, I think we should tackle the major misconceptions I’ve seen out there about it.  First and foremost this is an eraser that is meant for small jobs and nothing more.  A 2.3 mm eraser that is 2 inches long is certainly not going to last long if you use it to erase an entire page of text or a significant part of a drawing.  Second, this is not going to be a cream of the crop eraser when it comes to removing every last line and trace of a mark.

Now the good news, the Tombow Mono Zero Eraser is great for erasing precise portions of your work such as in a drawing, an intricate chart or graph, or in something that you requires precision.  The sample above shows how well it does with erasing a standard #2 HB pencil at varying pressures.  As you would expect the hardest and darkest mark was the one that didn’t completely go away, but it still did an excellent job.  I would definitely recommend the Tombow Mono Zero Precise Eraser for anyone interested in having a very precise erasing tool or for anyone that just wants a cool accessory for their pencil case.  Thanks again to our friends at JetPens for always providing such cool office supplies for us to review here.
