This is a wonderful decorative tray. It has a smooth finish and a beautiful design. - Material: Wood (I believe it's Japanese cypress) - Design: Radial - Bottom: Flat - Finish: Urushi lacquer wiping I understand that the bottom is finished by Yamanaka woodworkers with a high degree of precision, allowing it to adhere closely to flat surfaces. My grandfather purchased it at a high price and displayed it with great care, never using it. However, there may be minor scratches that I haven't noticed, so this description is based on what I can see. Please check the photos. Thank you for looking.
