This is a sake bottle made from natural bamboo. The bamboo pattern is very beautiful, and it makes the sake taste even better. It has a groove for easy pouring, and the craftsmanship is meticulous. I bought it because I liked it, but I haven't had a chance to use it, so I'm putting it up for sale. Diameter: 6.8 cm Height: 18 cm *Please refrain from price negotiations.
