Artgum is a type of eraser commonly used by artists and students for its ability to remove pencil marks without damaging the paper. It is made from a soft, rubbery material that crumbles as it erases, effectively lifting graphite while leaving minimal residue. Artgum is particularly favored for its precision and gentle touch, making it suitable for detailed work. Its unique texture allows for clean corrections, making it a staple in art supplies.
