Originated from the Kadazandusun ethnics of Tambunan district, bamboo pipes are tied together in a double-layered raft formation and inserted into a hollow gourd that serves as wind chest. Small lamellae of sodi of the polod palm are affixed to the lower end of the pipes that function as reeds. The bamboo and gourd are then joined together using special gum made from beeswax (sopinit) or free sap
