Thank you for viewing! This is a handmade cutting board made from ginkgo wood, a product of Kumamoto, famous for its Ginkgo Castle. We have a large and small amount of materials, but this time, we would like to offer naturally dried cutting boards at an affordable price. To effectively utilize the materials, the sizes vary slightly, but they are products that have been sawn to a thickness of 3 cm at a specialized sawmill. The photo is labeled s-1, but it is a similar product with a different size. Product s-5 1. Size Length: 45 cm Width: 24.5 cm Thickness: 28 mm Price: 4300 yen After purchase, we will carefully polish the front and back surfaces with sandpaper before delivery. Thank you for your understanding.
