This is a handmade wooden flower vase. It was made using Japanese cedar wood that was felled for work. It has been waterproofed, so it should be fine, but if you're concerned, please use it as a decorative pot. * Although it has been carefully finished, please purchase only if you understand that there may be slight unevenness in the carving, etc., due to the handmade nature of the product. * Cracks in the wood may occur depending on the usage and storage environment.
