Review – Tombow Mono Zero Erasers

A few years ago I was aiding my brother in the search for a good separate eraser to go with lead holders (that often don’t have their own erasers), and that lead me to review the Sanford Peel-Off Magic Rub, which is essentially a Magic Rub eraser in the same body Sanford uses for their Peel-Off China Markers. And to me that was the answer. I knew there were mechanical erasers, but they were mostly cheap little things, or not available in the stores I frequented. It wasn’t until a few months ago that I found the potential simple, high-quality solution of the Tombow Mono Zero mechanical erasers and I got them as fast as I could. Are they up to the task?

The body is super simple, being a cylinder about the size of a pencil and a little over 3½” long. It comes in 2 different colors: silver for the round eraser, and black for the rectangular one (it’s made of plastic either way). At the front there is a step-down to the “lead-pipe” of sorts. This “pipe” being cylindrical for the round and flattened for the rectangular is the only other main physical difference between the two. The (lead/eraser) pipe is a nice, stiff metal that cleanly guides the eraser as it extends. On the back, there is a non-removable, simple push-click mechanism with an integrated clip. The clip is good but not superb at clipping, while having the advantage of being very structurally sound (something most plastic integrated clips are not). On the top of this mechanism is a sticker with the eraser’s sizes: 2.3mm in diameter for the round “small” and 2.5mm x .5mm for the rectangular “slightly less small”.

Performance is good; the click mechanism is sound and has a satisfying feel, retracting and reloading are simple and both done from the front end (reducing the number of failure points but also making disassembly functionally impossible). The erasers are of the white variety and erase very well. They aren’t the absolute best I’ve seen and they won’t get rid of every single mark, but they are both quite tiny and precise, making them very useful in those fine detail areas other eraser wouldn’t even be able to get to.

They are very good erasers, but more as a set to complement others than on their own. For writing, pocket and backpack sketchbooks, or those who do a lot of detail work, they will be fantastic, especially if one gets both to use in different situations. But for general use, they obviously don’t have the huge, quick-erasing capabilities of a standard eraser, and I’d imagine that in most people’s use cases they’d augment and not replace one. Still, I am one of those people who like to write and do finer-detail drawings more often than other types and they have earned a place in my pencil bag that I don’t see them moving out of any time soon. So if you’re looking for a fine mechanical eraser to easily carry around, fit in with your pencils, or do detailed work, I’d say take a look at these.

Review – Sharpie Black Retractable Pen

So you want to ink a drawing you did, but you can’t find Microns, or any other technical pen. You certainly don’t want to use a ballpoint. What do you do? Well, the Sharpie retractable pen may be an answer. The black version, to be precise.

The pen itself is a shiny black that gets finger prints on it constantly, though it cleans easily. The body of the pen starts out wide and tapers toward the rear of the pen. Near the front is a rubberized grip section with some grippiness to it. Sharpie pen is written on the back near the clip in silver. The pen looks like it can be taken apart in several places, but it can’t.

The clip is metal, it’s rather stiff and doesn’t easily go into or out of a shirt pocket. The click mechanism in the back for retracting the pen feels solid, but the plunger is loose and feels a little flimsy.

As for the most important part: the tip. It’s a fine tip, with the standard very black Sharpie color. It puts down a fairly smooth line. I would compare it to a Micron 01 or that range, but it’s really slightly smaller. The tipping material is very stiff and doesn’t like to bend, which leads to less line variation but a longer usable life. It’s not a permanent pen, or at least permanent like the markers. It writes and sticks on most surfaces, but not on all, but it is very black on everything.

Overall is it going to replace a good technical pen? No, but it is very good for inking in a pinch or if you want a less-used line width in your art. It writes well, it looks good. The main problems for me stem from the fatness of the pen and the cheap-feeling mechanisms. Is it for you? Maybe. I’d recommend trying it out and maybe keeping a few around just in case.
