The "Dual Flexible Untangled Retractable Pet Leash" sounds like an advanced, high-tech leash designed to make walking pets easier and more enjoyable. Here’s a breakdown of what such a leash might feature:
 
Dual Flexibility: The leash has a dual mechanism that allows for smooth, tangle-free operation. It might have separate control mechanisms for adjusting length and flexibility, accommodating different walking styles or environments.
 
Untangled Design: An untangled design could refer to a feature that prevents the leash from twisting or tangling, which is a common issue with traditional retractable leashes. This might be achieved through a unique reel design or a swivel mechanism.
 
Retractable Mechanism: This feature allows the leash to extend and retract automatically, giving your pet freedom to explore while still keeping them under control. The retractable function is often operated by a button or trigger on the handle.
 
Durability and Comfort: Given its high-tech nature, the leash is likely made from durable materials to withstand pulling and rough use. It might also have ergonomic handles for comfort during extended walks.
 
Additional Features: Modern retractable leashes often include extras like built-in LED lights for visibility, a waste bag dispenser, or even a brake system to lock the leash at a desired length.
