One of the earliest known dinosaurs to have flight feathers, this four winged dromeaosaur was a glider instead of a flier. And its one of my favorite dinosaurs! This model has a mechanism in the head that allows it to stick open and snap shut when triggered. Because this mechanism is 3d printed with the model snap quality may vary. model prints 14 inches in length and is fully articulated. single or tri colors are available and model has customizable eye color. If unspecified random colors will be used, with modern birds serving as inspiration for what is chosen. 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.
