Faber-Castell Perfection Eraser Pencil with Brush - Precision Correction for Artists & Drafting - Perfect for Sketching, Drawing, and Graphic Design Projects

If you enjoy coloring in adult coloring books, This eraser is a must. I have used it to remove colored pencil, gel pen, & even marker as long as I erased it right away. This won't erase markers that bleed through the paper such as Sharpie markers. I have erased Stabilo Fine Liner markers though I had to do it immediately & very gently. This eraser is not meant for large areas. It is great for when you go out of the lines or change your mind on the color of the center of a flower. I have used it in areas as large as a nickel around. You need to be gentle and pay attention to the paper. If the paper is too thin, you could tear it. I have used it in coloring books with thinner paper. As long as I was gentle, it was fine. I couldn't always get all the color out if it was a dark pen. But, colored pencils have come out completely or if I was erasing a dark color from a nickel size area, enough came out so that I could use another color over the area I had erased and it looked just fine. It works fantastic in small areas because you sharpen it just like you sharpen a pencil, just not to such a fine point. It lasts a long time. So, even though it may seem expensive, it can make all the difference in how you view your art work. I love using gel pens. This is the only eraser I've found that erases gel pens when I have occasionally gone out of the line. I rely on the reviews of others when I am considering making an online purchase. If you enjoy coloring in adult coloring books, you have to add this to your supplies. You won't be sorry.
