Natural Whetstone Maruoyama Ao Suita renge

Size: 220 × 85 × 70 mm
Weight: Over 3,000 g

This is an early-production piece of Ao Suita from Maruoyama.

It was purchased for approximately JPY 300,000 at the time and has been carefully protected with cashew lacquer.

This is an exceptional stone that produces a remarkably beautiful Uchigumori-like finish, making it especially suitable for fine polishing and finishing.
