Obstinate AF Dragon. Same dragon. Same absolute refusal to budge. This version drops any pretense. AF means as f*ck- and this one is for the people who want to be unambiguous about exactly how obstinate they are. Which is: extremely. This mug is for the person who looked at the standard Obstinate Dragon and thought: not strong enough. Who is not just obstinate but obstinate AF. • Ceramic, lead and BPA-free • 11 oz: 3.8″ height x 3.25″ diameter (9.6 x 8.3 cm) • Dishwasher and microwave safe Obstinate AF. Non-negotiable.
