Townew R01F Transparent Refill Ring

The TOWNEW R01F trash bag has a distinctive shape to enable the self-sealing and self-changing features to work. With two sealing types, Regular and Overload, your TOWNEW T Air Lite will adjust how much bag material is needed in every seal. Each refill ring contains 25 4-gallon-size bags, but when your Trash Can is overloaded, it will release more bag material. As a result, it will decrease the bag count in each refill ring. That is the meaning behind "up to 25 bags in each refill ring"
