Kendama

A kendama (けん玉 ?, also written as 剣玉 and 拳玉) is a traditional Japanese toy which consists of two wooden cups of different sizes placed on the center of a wooden spike and smaller cup with a ball connected by a string. In English, kendama may be referred to as ring and pin and bears similarities to the classic cup-and-ball game, known in the Latin American world as balero. The principle of these toys are the same: catching one object with another, where both are joined by a string.
