Precision polishing is possible with a multi-stage abrasive surface. - Brand: BEST Whet Stone - Size: Approximately 11.5cm long x 5cm wide x 1.5cm high - Features: Multi-stage abrasive surface - Condition: Almost new. I purchased this quite a while ago and had it stored away. The box is slightly dirty. I don't remember using it, but the main body has very slight scratches. Therefore, I've listed it as "almost new." Otherwise, it's clean. Please refer to the photos for details. Thank you for looking.
