High Compatibility: This product includes 12 replacement bags, fully compatible with most standard diaper pails on the market (such as Tommee Tippee, Twist & Click, Tommee Tippee Sangenic Tec, Tommee Tippee Simplee Sangenic, Spross, and Littycat). Large Capacity: Each bag is 4.5 meters long and 26 cm wide, holding up to 320 diapers (capacity varies depending on diaper size). The high capacity saves time by reducing the frequency of bag changes. Premium Material: The bag film is made of high-quality polyethylene; it is safe and odorless. Odor-Blocking & Antibacterial: The film features a thickened antibacterial layer and undergoes anti-odor/antibacterial treatment to effectively lock in bacteria and unpleasant odors. Easy Installation: Installation is quick and easy; please refer to the instructions in the images. (Diaper pail not included; a diaper pail is required for use with these bags.)
