Do these erasers work on colored pencils? And, if so, do they work on ALL colored pencils, or only Prisma colored pencils?

To tell you the truth, personally, I feel that they smudge way too much....but I was using these erasers for a hvac architectural planing class

They work moderately well on colored pencil shading, but not as well on hard lines with sharpened colored pencil. The waxier/oilier the colored pencil lead, the worse the eraser works, the chalkier the better. Of course, the eraser is amazing with most all graphite and charcoal.

When I bought my pencils I researched and found the following: Sharpen a few regular graphite pencils between times when you sharpen some Prisma because Prisma colored pencils have such a high wax content, they often get a build up in the sharpener and slow it down. By sharpening a graphite/ regular pencil sometimes it helps keep the build up to minimum and sharpener lasts longer. I would suggest getting a sharpener designed for Prisma if you will use them exclusively.

Any dry-erase ("white board") marker will write on them, and any similar eraser will then erase it. For my children I really like the Quartet ReWritables Dry-Erase Mini Markers, but I'm considering getting them a regular-size eraser for better color erasure.

I would not use it for prismacolor pencils. It has a hard time with some of our colored pencils, especially the softer ones. We use it with our generic and crayola colored pencils because I don't mind if I have to resharpen after it rips the lead out, but prismacolor pencils are so expensive that I don't want to waste any of it. I use a manual sharpener for prismacolor.

Prismacolor colored pencils are wax based, so unlike the usual Crayola, they do not leave a "powdery" substance behind. However, like Travis mentioned prior to my comment, they will eventually leave a waxy buildup, but it's more of a thin film that you can scrape off gently if it bothers you. Other than that, there's very even coverage, and they should work fine.

Just seems to me the erasers should be available where ever they sell the Uni Kuru Toga Roulette models. I haven't looked yet or tried to find them but the specs used to make the pencil, I would suspect to be the same. Now I am wondering also. Very annoying not to be able to replace your eraser when it wears down. VERY !!

Yes. I have sharpened Crayola colored pencils and it always works great for me!

Those look to be the correct refills. Are you sure you are looking in the right place for the eraser? If you take off the cap and put it on the back for the pencil, then the small silver cap that you use to advance the lead can be removed to reveal the eraser. I hope this helps.

As far as I have found out it really all depends on the paper. I used them on watercolor card stock and bamboo paper to do some art and they did not bleed through. Now I used them in a journal that I'm doing and they DID bleed through. They are very nice to use and they write and color really smoothly I would suggest that you try it on a corner of the paper on somewhere where its not noticble I really hope that this answers your question and that if you get them you enjoy them as much as I do. (I also really like using colored pencils too)

There are 3 different color refills...you remove the refills by unscrewing the pen..the eraser doesn't come off.

I have sharpened colored pencils in my sharpener. I sharpen hundreds of No. 2 pencils a week. I found that the colored pencils gummed up the sharpener a bit. I also have more than one sharpener because I sharpen so many pencils. If I did sharpen colored pencils, I would use one of my older sharpeners for colored pencils and keep my better sharpener for the demanding job of sharpening all my pencils. I also no longer sharpen foil/plastic wrap pencils. These pencils have cute pictures and designs on them, but they also dull and gum up the blades.

You can use on glass, i would say that the way a marker wipes off is highly dependent on which type of eraser you use. If you use a microfiber cloth, it will most likely wipe off very well. I'd suggest testing this in a small area with a dry erase marker you have laying around.

They are not permanent is used correctly on a non-porous blackboard (magnetic chalkboard). I write and then erase (using a water/baby wipe or damp sponge, sometimes WEEKS later) and then rewrite all the time for my baby boy's "Monthly Birthday Board". Having said that, I'm not sure if they are permanent if used on a paper surface or on cloth, since that is not their intended use.

I'm afraid I can't be much help to you. I bought it after checking all the pencil sharpeners I could find, the recommendations and details of each. It was for my great grandson who needed one for school work. I know it worked well and he liked it, but am not sure about colored pencils or water color pencils. Sorry.

Don't know. I have not used them on black board. They work on white dry-erase board so should work on black if same material.

It depends on the tooth of your paper. On very soft and rough paper they aren't erasable. On smooth, or something like velum, they erase pretty well, but will also smear more.

I'm not sure..... I tend not to use the eraser on the pencil (I prefer using a Staedler Mars plastic eraser). Sorry I couldn't be more help.
