You are purchasing a pack of random authorized Layers in Green Articulated Baby Axolotl Tadpoles. They are printed from PLA. The size is 1 3/4"long and 1 1/4" wide. They are not articulated. Please check my other listing for the larger articulated ones if you are looking for articulated. They are not a toy so they can break if you are too rough with them. With 3d printed art, each piece will be unique so please allow slight variations in color distribution. The same type and color of filament will be used, but the colors may be positioned differently. I also accept requests if you are looking for a different color or size. I am an authorized seller of Flexi Factory and Cinderwing3D prints. Choking Hazard, Small Parts: Not for children under 3 years old.
