• Dual-Use Design: Typically features a two-part composition where the white part is used for pencil marks and the gray (sand) part is used for ink, including ballpoint pens, neutral/gel pens, and water-based pens.
• Abrasive Sand Technology:
  
  The gray portion contains a fine scrub or "sand" that works by gently
  
  removing the surface layer of the paper where the ink has bonded.
• Traceless Correction: It is designed to leave minimal traces or smudges, providing a clean correction on appropriate paper types.
• Compatibility: Effective for erasing erasable pens, standard ballpoint pens, gel pens, and pencils
