It's best product for beginners

The media could not be loaded. Not stretchableNot moldableHard as rockFirst I thought it was defect in just this product, then watched some youtuube video and came to know this brand is producing these low quality kneadable erasers lately.

this is very good eraser but quite expensiv its only one piece of 2x4 cm and i got criticised by my parents for this but eraaser is good

Good enough not bad

Average product

theeraser is good

Eraser is good but while buying check description as it only have a single piece

I ordered it once last year which was working better but the one I ordered recently is awful quality which is very hard and doesn’t mend at all and is even difficult to erase with.***I won’t suggest buying this*** .

Erases pencil crayon very well

Publican una caja y mandan solo una goma me parece que es una estafa y quiero devolver este artículo porque me parece que es un timo y un engaño, no puede ser que cobre por una goma lo que vale una. Caja, como es la publicación, quiero hacer una devolución inmediata.

I thought because of the brand being so good at pencils that this would be of the same heightened quality. I thought wrong.Utter crap

Great eraser

A kneaded eraser is basically a soft, slightly tacky rubber (Doesn't stick to hands or paper) that you can mold in various thicknesses to erase various kinds of dry media with light rubbing. Most common is graphite and charcoal. The advantage of them is that you get a LOT of use with each eraser. This one is no exception in that when you "fill" up a part of the surface, you just fold that spot in and get another sticky spot ready to go. This can be done many times over because the dust that you pick up just gets molded in and disbursed through the rubber. So even if it looks dark over time from picking up a lot of dust, it's still very usable. I haven't had any issues with this eraser hardening/drying out either and Ive had it for a few months so chances are that means it's usefulness stays consistent for a long time. But longevity is not their only strong point, they also do not leave that rubber flake residue that regular erasers do because the eraser does not wear down. So it's less messy as well.Performance wise on paper I'd say it performs as well as a regular eraser in that it'll pick up all it can from a spot but any embedded marks (like pressing too hard on paper) will end up staying and you'll probably have to carefully use fine sandpaper (If you do it too rough, you can tear the paper or make the surface too "rough" and it'll look off at that spot.) or something to actually get the color out of the paper's fibers. One thing it can do in this regard over a regular eraser is that you can pick up color just by "dabbing" the paper. So you don't need a rubbing motion to get color off, you just need to touch it a few times. Colored Pencil/Pencil Crayon doesn't really come off on this super well (nor does it on a regular eraser) because it's a type of wax, but it will likely get the paper's surface down to a light enough color that you can put other colors on top of it again and fix whatever you wanted fixed. If not, sandpaper I guess. The best thing to do is just not press too hard so you never need sandpaper of course.Couple of things to note with this style of eraser though is that as you rub with it, no matter how softly you do it, it will change shape. So if you squished a sharp edge out of it to do some detailing work, you'll have to watch it so you don't erase too much as it gets thicker. Also, because you do have to knead it often to get the surface sticky again after picking up stuff, it may mess with your workflow. To store it, you can't exactly leave it out like you could a regular eraser for extended periods of time because random dust particles in the air sticks to it just as graphite will. So you might want to put it in a small zip-top bag or something to keep it as dust free as possible. But I don't think those are reasons not to try one because as you get the hang of using one, you start to adjust automatically such as kneading it one handed while you are thinking of what to do next or squishing it to keep making yourself a sharp edge with it as you go. Plus they're pretty cheap, so you aren't investing too much in one to try.
