Based on the original dragon, this ancient bird has a big bite! This print has a spring mechanisim in the jaw allowing it to "lock" when opened and snap shut when the tongue is pressed. Because this mechanism is 3d printed with the model snap quality may vary. model prints 13 inches in length and is fully articulated. only one filament may be used, but eye color can be customised. If unspecified a random matte or silk filament in a neutral color will be used. an eye type that compliments the main color will be selected randomly if unspecified. IMPORTANT: filaments other than PLA are not available on biter models. please see "about material type" section.
