Black Skull Aztec Death Whistle! Blow into this and it imitates a human scream! 3D Printed.

To use: this item is best used with pursed lips and by blowing into the hole at the top of the skull. You may have to adjust the angle of your airflow. This item isn’t intended for a full-blown scream replication, it is more of a light roar of screams in the distance.
