In my quest to make better art, I try out all sorts of things including art erasers. I used to specialize in their use in art school. As one design teacher said, "You do magic with erasers. I never think you can clean your margins up, but you always do." Lately I've been using a lot of colored pencil to create original art for my jewelry. That means excursions into the land of art erasers. I learned a little bit about how some work compared to how they work with a regular graphite pencil.
In order, they are Sakura Foam, Mitsubishi Uni Boxy, Tombow Mono Sand, Pentel Mark Sheet, Tombow Mono Zero, Gum Eraser, Kneaded Rubber, and just for fun, a 30 year old +/- Staedtler Mars Plastic from when I was in art school. I like different art erasers for differest tasks.
Favorite Art Erasers
Sakura Foam is my favorite. It feels like foam and it's the best eraser i've found for Prismacolor. It's also outstanding for graphite drawing. Mitsubishi's Uni Boxy is a close second. Plus it's cool to use a black eraser. Comically, number three is the 30 +/- year old Staedtler Mars plastic eraser from art school. It still does the job. Go figure. They all do well with cleaning up margins.
Other Art Erasers
In the middle of the pack are The Tombow Mono Sand, Pentel Mark Sheet, Tombow Mono Zero art erasers. The Mono Sand is supposedly good for ink, but I haven't seen it happen. The Pentel Mark Sheet and Tombow Mono Zero are good for tight areas on graphite but not impressive on Prismacolor.
Specialized Art Erasers
The two that I find I used in the most specialized manners are the gum eraser and the kneaded rubber. Gum erasers are good for lightening graphite drawing. Kneaded rubber erasers are awesome for picking up those little bits of colored pencil that try to smudge your drawing. Both are also very good for cleaning up margins.
If I could have only one, it would be the Sakura Foam. What about you? What would you choose?
