These erasers are great. I have a hard time using the eraser on the pencil, so these are perfect for me. They are bigger and easier for me to hold onto when I need to fix a mistake. They erase completely with pencils. They are supposed to work with erasable ink as well, but I don't have any erasable pens to try this claim.
