C.K.K. Japanese Rust Eraser

This rust eraser, or Sabito - ru, is harmless and elastic. Use it like an eraser (splash some water or light detergent for better effect) to remove rust and stain from knives, bicycles, or any tools. Be careful with using it on fine jewellery, or any glossy surfaces, as the abrasive particles can leave scratches.

Comes in 3 variations of roughness:

• Blue - coarse
• White - medium
• Red - fine
