Is it possible to erase anything I've done with colored pencils?

Usually, you can't erase colored pencils completely, especially when the line or shading is very strong. However, a Tombow mono eraser is a great tool to use for quick fixes and touch-ups. It gets deep into the surface, which is awesome when you need to erase highly saturated or dark colors. It's also great because it's so small, which helps when you need a lot of precision to touch up tiny areas like the eyes in your drawing. If you are going to erase anything you've made with colored pencils, avoid using lots of pressure because it alters the paper's surface. If your paper is low quality and very thin, you might rip or warp it.
