Trophy skulls with purported colonial-era ethnic engravings were widely sold online at various platforms. In 2005, Royal Malaysian Customs Department seized 16 human skulls with engravings that were purported to originate from northwest of West Kalimantan province, somewhere between Pontianak and the Sarawak border, and bound for an unknown buyer in Australia. These seized skulls were transferred to Sarawak State Museum in 2015.[19]
