I’ve always wanted to finish a block eraser. To use it until I had a little piece too small to be used. But I always lose them before I get to the end. I have two erasers now that I’ve managed to keep for almost a year each.
…I think I may be able to do it… One of them is one of those brown Able Rub erasers that leaves huge shavings behind when you erase. That’ll be the winner, I think.
