Sakura Crepas Eraser Foam Eraser Double 60 5P x 20 Pieces RFW-60-5P (20)

These are doing a good job for me. I am taking calculus 2 right now consuming more stationary than I have for any english class. I use nice mech pencils with cheap notebooks. Most mech pencils have poor erasing functionality, often being too small and/or hard to replace, requiring you to remove a cap that you will certainly loose, and almost always they will extend the lead when erasing.These erasers will almost always erase even dark lead completely. The only time they won't is if you have been handling the exposed area extensively (like nervously fidgeting with it) and loaded the surface with oil from your skin. They also will not remove indentation from excessive pressure when writing (nor will any eraser).They really shine when working on thin notebook paper. Because they generate less friction, they can erase with out crumpling or tearing the paper.

This is a superb eraser. It erases clean and the fragments are easily whisked away. It’s the best eraser I have used in over 40 years of drawing, sketching and writing.

These erasers work so good. My students fight over them. Some kids are notoriously heavy handed when writing, but these erase anything! Love them!

These erasers are fantastic! I had never heard of a foam eraser before, so when I saw these on Amazon and after reading the reviews, I took a chance and ordered them. I have several hobbies that require marking with a pencil, such as woodworking, leatherworking, scale modeling, technical drawing, etc. This means I have the opportunity to use these erasers on many different surfaces. I could not believe the difference between these foam erasers and standard rubber or polymer types. These erase every last trace of the pencil marks. If it weren't for the depression left from pushing down on the pencil, you wouldn't be able to tell there had ever been a mark made there! These erasers leave no residue, no smudges, no color transfer, literally nothing is left behind. If you do a lot of erasing like I do and you are debating taking the plunge to foam erasers, do it! You will not be disppointed!

I am so happy that my son found these erasers, there nice smooth to erase and best if all they clean really well. I. would prefer these to your kids for school because these are the best. Also, when you erase, in most like erasers, the dust goes off somewhere and it makes a terrible mess but these erasers, the dust sticks on so that it will be easy for you to clean. Very good deal. MUST BUY PRODUCT. :)

It's a worthy opponent in the eraser world for sure. I do think it's best for writers, as it tends to wear down quite fast - but it is impressive in that it leaves almost NO MARKS on the paper... I find almost no trace of lead and it's very gentle on the paper.. The debris rolls right up and is gone. It's pricey, but it's pretty good.

Been using them for a while now and must say they're good quality. The protective sleeve feels firm on the hand and is easily slidable to adjust how much of the eraser you want to be exposed on the top. The eraser barely leaves any marks and my only complaint is that it isn't fully stain-resistant, but still is harder to stain than other erasers. Certainly is better than your average pink eraser or Pentel's Hi-Poly erasers.Conclusion: One of the best erasers you're going to find on Amazon.

Upon first using these erasers, I immediately fell in love with them.I highly recommend over erasers from other brands like Pentel and Staedler. These erasers use a different technology (so called foam technology) that simply works way better at doing what they're meant to do: erasing.The only downside to these erasers are the fact that they wear out much faster than their plastic counterparts. However, I feel as if you are more likely to lose an eraser than use it up until it's no more.For the money, these erasers are absolutely the best you can buy. Highly recommend.
