These symbolic beads have been discovered in many different regions within Southeast Asia. Some of the locations in which these beads were found are: Central Thailand sites such as Ban Don Tha Phet, a Peninsular Thailand site, Khao Sam Kaeo, Coastal Vietnamese sites of the Sa Huynh culture (Sa Huynh, Giong Ca Vo, Phu Hoa) and, in the Philippines, the Tabon caves in the Palawan island. Additionally, beads were encountered in the Manunggul Cave Chamber A in Palawan, an island in the West Philippine Sea nearby to Sulu.
