Body Size: Diameter: Approximately 45mm, Height: Approximately 165mm Wooden Box Size: Length: Approximately 185mm, Width: Approximately 65mm, Height: Approximately 57mm Thank you very much for viewing this item from the many listings on Mercari's website. Judging from the packaging, I believe it is unopened and new. It is used in the tea ceremony, on the ash near the charcoal of the brazier, or in a censer. It is believed to have been purchased about 10 years ago, but because it has been sealed well, it should be perfectly usable. Also, there is no mention of an expiration date on this item or the included pamphlet, although there is a description such as "wet with lukewarm water when drying." Please refer to the photos of the instruction manual for details.
