Soft gum compound lifts graphite and charcoal without abrading paper fibers, the kind of gentle removal that matters when you're working on delicate surfaces or preserving underlying layers. Factis erasers wear away as they work, crumbling into particles that carry away marks rather than grinding them into the paper. This self-sacrificing action keeps the erasing surface clean and prevents the smudging that happens when conventional erasers get loaded with graphite.

The pliable material conforms to paper texture, reaching into tooth without flattening it. Useful across drawing papers, illustration boards, and even fabric surfaces where harder erasers would damage fibers or leave burnished spots. You can work over erased areas without encountering the slick resistance that abrasive erasers create.

General's offers two sizes: large measures 2.16 × 0.925 × 0.51 inches for broad corrections and tonal adjustments; small measures 1.12 × 0.925 × 0.51 inches for detail work and tight spaces. Both maintain the same soft lifting action that makes gum erasers essential for finished drawings and archival work where surface preservation matters as much as mark removal.
