Unfortunately when you write caveman style (with a pencil) there, absurdly, is no delete button. Just use our Delete Eraser, it will feel almost as comfortable as typing on a keyboard! As you're erasing, just look forward to the future when you wont even need erasers or keyboards and youll be able to delete things with your mind!
Warning: Do not try to press or squeeze this eraser to magically erase what is on your paper. Thats not how an eraser works!
