A Burger King ad mug. Among restaurant-related ad mugs, this one is overwhelmingly popular, and due to its scarcity, it's a difficult item to obtain. Be careful, as there are many fakes. The mug itself comes in two types: the normal type with a thin handle that fits two fingers, and the ultra-rare round handle. The round handle is incredibly rare, so it has a powerful aura! If you're interested, don't miss this opportunity!
