Broadly speaking, an usucha-ki is a wooden vessel with a lid, designed to hold powdered tea for making thin tea(usucha).
Traditionally, usucha-ki are hand-carved from wood or bamboo, and usually are lacquered. Today, mass-produced plastic usucha-ki are also available. The name "natsume" comes from the natsume or jujube fruit, which some usucha-ki are said to resemble.
