Review – Staedtler Mars Plastic Eraser

Interesting tidbit with this review; I was ordering a replacement for this product (because spoiler: I liked it) and I ended up with something that I wasn’t expecting. While my original Mars Plastic eraser came in a humble card sleeve (as most still do) my new ones came in a fancy plastic swivel case. So this review will really be two parts. One for the eraser itself, and another for the upgraded container they can come in.

The eraser is a standard seeming white plastic/rubber rectangular prism that measures about 2½ x ¾ x ½ inches and is marked in a regular pattern subtly with the Staedtler logo on two sides; the four smaller sides are essentially flat. Since it is an eraser there isn’t much more to say about the looks, but how does it work? Well, I really like it. I go back and forth between hard and soft (kneaded rubber) erasers. I’ve currently moved back to the hard erasers because I can see when their ability to erase starts to be diminished more clearly (by being shorter rather than slightly darker). In my experience it has erased almost every pencil line I’ve asked it to, and it is better than the ones usually found at the store (save Magic Rub), but comparing higher end erasers is very difficult. They all do their jobs well and it’s mostly a matter of personal preference (and sometime pencil choice) as anything else, but that’s where a fancy plastic case might stand out and make a difference.

The case is slightly larger in every dimension (duh) than the eraser. The top and bottom are made to resemble the traditional card-wrapped eraser, with a white bit extending from the blue eraser identification part. A larger Staedtler logo covers the pivot on one side in this white area. On this white end attached to the pivot on the inside is a cut-out box that is about an inch on one side and an inch and a quarter on the other. This box has eight small ridges on the inside to grip the eraser, and it pivots 180 degrees from having the eraser tucked inside the rest of the case to being fully exposed. It can go farther, but at risk of breaking the back of the case. This allows for easy dispensing of the eraser with one hand and provides a nice sturdy handle when erasing. It also protects the eraser from getting gunky or gunking up other things (the inside does get a bit dirty/gunky sometimes, though). I’m a fan of the case (but being nitpicky the two smallest ends are rounded off and the eraser will not want to stand up on them).

So in the end the Staedtler Mars Plastic is a good, but not exceptional, eraser. It’s not like it erases every pencil line in one stroke, or is virtually crumb-less, but it does get most pencil lines with relatively few crumbs. It works well, and I really like the case for the convenience and protection it provides. I’ve been using it (and flipping it open compulsively) for a bit and it doesn’t show any signs of breaking soon. Though it does make the eraser a considerable bit larger and limits use of about half of it. It’s a nice change of pace and experiment if one wants to spice up their eraser life.

Review – Sanford Peel-off Magic Rub

These days most pencils have their own erasers, but some still don’t, especially older models that have been in production for years and are still very good at their jobs. And even many of the new pencils don’t have enough eraser for the life of the pencil. Separate erasers are still a large market. But what if the eraser came in a more convenient package? The Sanford Peel-off Magic Rub intends to solve that problem.

The main body is simple: it’s a tube of paper that is continuously wrapped around itself and sealed with a sticker. On the sticker is the main information for the product. There is a string attacked to break the sticker seal and allow for the paper to be peeled back when the product is used. The paper and eraser tip can also be sharpened, but I wouldn’t recommend this. The core of the utensil is a tube of Magic Rub, which is a very good white eraser. Sanford’s Magic Rub erasers are easy to use, resist drying out, remove quite a bit of graphite, and aren’t as hard on the paper as some other erasers. They aren’t the best erasers out there, but they are very good ones.

And that’s really it. The entire “pencil” is slightly thicker and shorter than a standard pencil. But it fits in most of the same places and works very well. If you have a lot to erase, and don’t like the potential of breaking mechanisms with a mechanical eraser, I’d give this one a shot.

Review – Paper:Mate Sharpwriter

Papermate has been making pencils for a long time, and one of the simplest and least expensive mechanical pencils available is one that they make. These pencils are some of the cheapest on the market from a name brand, and always come in packages containing a large number. They are almost universally recognized as one of the lousiest pencils to use, but is that reputation deserved?

Starting at the back, it’s got a small, pink eraser that does indeed erase (quite well, actually,) but, like most erasers at the back of pencils, it won’t last very long. Moving down from that, we have a basically straight and plain body, with a terrible “clip” near the eraser (it doesn’t actually clip on most things the thickness of shirt pockets). The basic information about the pencil is physically molded in the side, with no other features on the barrel. It looks slightly slippery but does grip with no problems.

20150503-225632

At the front of the pencil is the lead-advancing mechanism, which one must twist both to extend and retract the lead. This is inconvenient, but not more so than a top click. This twist mechanism is flimsy and easy to break if one goes too far, but not too noticeable when writing. The lead is technically refillable, but the pencil is almost treated as disposable, so it isn’t worth it.  The lead that comes with the pencil is fine: it’s a #2 and it works fine for most purposes, even erasing well with the eraser. There is also a “shock absorber” in the pencil (I believe it isn’t a special thing but inherent in the design) and it works!  You can press down quite hard and the lead will simply retract a few mm instead of breaking, but writing like this would be fatiguing and still cause the lead to break, since the spring is only absorbing force in one direction.

Is it a great pencil? No. Is it a bad pencil that will explode when you take it out? No. It works.  It’s a bit finicky at times, and I feel like I could break it with my bare hands and minimal effort, but under normal use conditions this isn’t a problem. The clip is the worst part, and if you need a good one I’d steer clear of the Sharpwriter. If you’re looking for the one pencil to have forever this is also far removed. But it is quite versatile and quite inexpensive. (Adam Savage of Mythbusters likes them: https://youtu.be/uN6vptYpo5I?t=2m15s) And if you lose pencils often, or are getting them for an office, I’d at least consider it.

Review – Scripto Oops

Sometimes, when going through life, you find some amazing idea that you can’t believe has been discontinued. I mean, how could they not be making money on that? Of course, there are many reasons for something to disappear, and in the case of what I’m reviewing today, the Scripto Oops, there are plenty of long erasers to take its place. But this one was the first I ran across, and I think it deserves at least a short review.

20150127-223939

The Oops is a pen-like item, with an uncapped cylinder as a push button on the back, and a functional, but not very useful, clip. One the side of the eraser is printed the relevant information for the company and item being used. At the section, the eraser becomes more “triangular” and ridges are added for grip in the facets.
Pushing the button moves plastic claws at the front of the eraser that push forward and then lock in the main eraser part. This mechanism is fairly sturdy, but does break over time. The eraser itself is better than a standard pink eraser, but not as good as gum erasers. In general, it falls well into the white eraser category.

Overall, I love the thing, and use it when I remember it’s around (and not lost in my pen cup). For art, I do tend to use higher-quality erasers, but for everyday use this is a great one and it fills all the roles needed with minimal streaking and removes enough pencil. It’s just a shame they don’t make them anymore.

Review – Prismacolor Kneaded Rubber Eraser

Recently, my erasers started running out of eraser juice, and I started having trouble with them. So I went to the art supply store looking for a replacement. I found almost my exact eraser, and one that was a bit cheaper, so I decided to try the cheaper one, the Prismacolor Kneaded Rubber eraser, out.

20140917-043500

Kneaded rubber erasers are cool. They can stretch and bend to get into small, difficult spots as well as wider spots. They can “clean” themselves, and generally don’t leave any eraser shavings. And while this is a good eraser, it isn’t as good as the ones I have used previously. It just doesn’t erase quite as well. Pencil is harder to remove, and stays bolder in indented lines. The eraser also rubs off quite a bit. There are still fewer shavings than one would get with a solid eraser, but more shavings than one should get with a rubber one.

So, if you’re just looking for an eraser that is better than standard or even high-quality solid erasers, I would recommend this one. It’s definitely good and gets the job done. But it certainly isn’t the best rubber eraser out there.
