When it comes to Erasers, I would recommend the gum eraser from the sketching pencil picture, Magic Rub erasers(for those who are on a budget), Sanford Union ink/pencil eraser(Yes, sanford has crappy pencils, but great erasers), and most importantly, the Factis Black 18 erasers.
Next is a random picture of some folders.
Okay, now for Painting. I like to paint ALL types of paint on the Aquarelle paper. It's simply great.
In terms of you general paint, I would go for one with no smell. It would probably do the best with paper.
If you like customizing, I would go for Testors or Games Workshop paints. Pictured are Testors Enamel Paints, Testors Aclyic paints, Window aker, sand paper films, plastic parts ement, sculpting knife, and various brushes.
