Lengthy but hopefully helpful. I rarely leave reviews, but.....After reading reviews for this and other brands for comparison (results and price), for the purpose of drawing I was unable to determine much from the reviews and cant help but SMH and feel sorry for the makers of a good product and for consumers trying to determine what to buy with some of the reviews for erasils. Many people simply "don't know what they don't know" about erasers -- those writing reviews and those trying to decide what to purchase. Maybe this will help....If you are sketching/drawing you should have various erasers in your arsenal (and also sketching lightly until your proportions and highlight areas are established before shading, especially heavily). You should also know the paper type (smooth, vellum, weight, gsm, etc.) and which medium you are using (graphite, charcoal, colored pencil, etc.) Different erasers perform differently... some are abrasive (great if that's what you need) and some are not (great if that's what you need). Some leave behind debris/crumbs (although no one likes crumbs, it's how they are made to work) and ones that do not (not a good option for all applications).These erasils (eraser pencils) are not intended to remove every last bit of graphite, colored pencil, or charcoal from your paper with a huge area of mistake with dark marks -- this will not be remedied with these erasils....not without paper damage anyway. They are quite rigid, so if you rub too aggressively with these (or other vinyl erasers) you will rub off the surface of your paper and ruin your artwork. You cannot use these as if they were gum erasers. And yes, unless you are using a kneadable putty eraser, they will leave behind debris...erasils are vinyl erasers. (Some people were not pleased in their reviews because these left crumbs behind. Again, it's an eraser.) They can be sharpened with a pencil sharpener to a point hence the benefit of these along with their size and ease of grip (don't sharpen to a long point; the tip will break unless you use very light pressure and may still break). Not only will they wear down and need replacing from sharpening, but also from use (all wear down from use other than putty, but gummed will wear down the fastest). In art, erasils are intended to lighten a small area of your drawing (Faber-Castell is, after all, a maker of art supplies) with medium to heavier coverage of graphite, charcoal or colored pencil, or remove more of the medium if light with less coverage. For brighter, smaller dots (eye specular) or thin line highlights (hair, fur, etc.), depending on the size of your drawing you can also gently use a thin eraser like the Tombow Mono or an electric eraser with a sharpened/chiseled edge or point (or simply don't lay down medium in that area -- or use a white pencil or white Gelly Roll pen to brighten). To "lift" larger areas of graphite or charcoal use a kneadable, putty eraser (there is information online regarding how to use putty erasers -- there are things to know!) either alone or before using a rubber or vinyl eraser in the same area.If using these erasils with writing, you can erase a stroke that isn't too heavily/darkly written. A #2 (HB) or lighter (H, H2, H4, etc.) pencil written with normal to light pressure will clean easily with an erasil without damaging the paper surface... depending on your paper. Heavier-handed writing or with a softer/darker pencil may clean also if the paper is smooth. These may also remove some ink. If using for writing on specialty paper, be aware of the tooth of the paper. The smoother, the better; the lighter the pressure, the better when it comes to erasing with erasils.If you simply want to erase marks without damaging your paper, gummed erasers will do that best; they will leave behind a lot of debris/crumbs. There are pros and cons to all erasers.... you just need to use the one that will do the job you're needing done (unless you never make mistakes, in which case you likely aren't reading any reviews on an eraser!) Each are just one tool in the box.[These erasils (and many other products) get a bad rap from those using them incorrectly or don't know they are using the wrong product for the job. With products that are more widely used for art but are also purchased for every day use, it's difficult for artists or those getting into art to get valuable feedback from "reviews." Even "people who draw" don't always provide the info needed to help determine if it's the product you need/want.... or a good product. (Sometimes a 1 star rating because they didn't like the color... it didn't match something in their home! (True story) Not helpful at all, skews the rating, hurts the maker unnecessarily, and wastes people's time reading.)] ...But I digress.... Like paper types, read a short article to understand your needs before buying and giving a bad review of the product simply because you don't know there are differences in erasers (as well as paper & various mediums) or that there is a correct/incorrect way to use some erasers. Do a quick search for eraser comparisons and don't read from the manufacturer... read from someone not making a profit from the product and is using it as you intend to use it.Erasils are vinyl erasers encased in wood. Vinyl erasers are abrasive to your paper surface (vinyl also comes in other forms). With a light hand and without the intent to remove loads of medium, they work as intended considering the paper being used. Using them on (cold or hot press) watercolor paper, for instance, however will likely result in the surface of your paper being damaged -- even some sketch papers. Many papers used in inexpensive sketch pads have a texture (fine or heavier) that will rub off, tearing the surface, if erasils are not gently used or if attempting to erase a mark in an indentation made from a harder pencil with a sharp point. This isn't only the case in art, but in writing as well as not all paper (or pencils) are made equally. And not all people write/draw/sketch with the same amount of pressure and pencil point.The brush on the end of these is for sweeping away the crumbs. I would prefer it were a bit larger personally, but is as big as the pencil will allow. (Artists don't like to brush these away with their hands as it smudges their time-consuming work requiring even more erasing if possible, and skin oil can also deposit onto the paper. I prefer to keep a small paint brush nearby. You do, however, want to brush them away before continuing with shading/drawing and shaking the paper clean is not always an option of it's taped around the edges. So they are handy, just not big enough for my preference. Having said that, all erasils offer the same size brush if they offer one at all.If you try & don't like these erasils, obviously you will & should leave whatever review you like, but hopefully this helps you determine whether they are right for you and your needs ....and whether the maker produced a bad product or whether it's simply the wrong product for the task -- before you choose to spend your hard-earned (or easy-earned) dollars.TIP: If you do buy to try, do some tests on scratch papers... different paper with different mediums before using on your art, decorative writing, etc. Get a feel for the pressure you want/don't want to use, the amount it will remove of each medium/pencil hardness, etc., because, by nature, they are rather hard/stiff/abrasive. I have not yet tried other brands, although I don't expect they will be much softer. Putting them into a pencil requires them to be somewhat rigid or the point would continually break with use. I think it's just the nature of the beast. (I'm practicing to make fewer mistakes I don't have to erase...Ha!)👍 Faber-Castell![ Photo: Graphite on white, 75 lb. inexpensive sketch paper with a light tooth (erasils will damage this paper if not used with care although it isn't a heavy or extra textured paper), with the use of a FABER-CASTELL ERASIL (in the fur/on the face) & Tombow Mono Zero eraser (mouth, fur, eyes). No paper surface damage. Drawing is unfinished, but the erasil's job is mostly done.What's harder than erasils? Determining when your art is actually "finished!" ;-) ](Shown simply for reference from "someone who draws" not a professional artist to display the lightened areas using this product.)Hope this helps ! Draw/write/erase on, fellow Amazonians!

Tu dessines ça t en prend. Plomb couleur y sont un atout précieux.

If you’re serious about drawing, these are so handy. They allow you to erase with so much precision, and then instead of sweeping off the eraser crumbs and smudging your work, you can use the little broom! They’re just fantastic. I love that there are 3, too. I put one with my charcoals, one with colours and one with graphite.

El producto superó mis expectativas y viene en perfectas condiciones.

Tendance à s'enfoncer un peu plus qu'une gomme classique dans le papier du fait de la dureté de celle ci donc certainement préférable sur un papier de qualité. Reste bon pour certaines finitions.

Loved the product. Can be used to shade as well as erase. We have relevant YouTube videos for uses, how to sharpen etc for any further details.
