The Tommee Tippee Twist & Click nappy disposal system, individually wraps each nappy, safely sealing away germs and odours. Our Twist & Click nappy bin – saving parents lots of trips to the outside bin. Drop a nappy into the bin. Twist the handle and feel the click. The nappy is now wrapped in multi-layer anti-bacterial film that locks away nappy odours and germs. The built-in plunger pushes the nappy down into the bin when you close the lid, keeping your hands clean and your room fresh. Each refill cassette provides enough anti-bacterial film on average to wrap up to 1 month’s worth* of nappies depending on the size and number you use. *Based on the average nappy usage across the few years of nappy changing. With Newborn you will change your bub more frequently so cassette may last approx. 2 weeks however, as your bub grows, the number of nappy changes drops as well as the possibility you will get out and about more often, the cassettes will last longer. Please be aware that twisting unit more than once between nappies or emptying disposal unit more often can so affect the longevity of your refill cassette.
