The 360 sealer diaper disposal system from Tommee Tippee is a new innovation in odor control! Super seal technology individually seals dirty diapers in odor trapping film. Pail comes fully assembled and the film is quick and easy to set up so you"ll be sealing dirty diapers in seconds. Each refill seals up to 100 diapers (of any size). Easy to use - just drop the diaper in the top and twist the dial to seal it away. No need to push your hand inside ensures a less messy and more hygienic disposal. The pail holds up to 30 diapers* and when it is full, it is easy to empty with no need to disassemble -just pull out the EasiSlide drawer & tear the film to take it out to the trash. *based on newborn size diapers.
