The enhanced sangenic tec nappy disposal system from tommee tippee is the only system to lock in odour by twisting and wrapping each nappy in an antibacterial film, sealing all odours away for unbeatable protection. The system is easy to set up, easy to use and easy to empty, meaning you can spend less time changing and more time with baby. The bin holds approximately 28 nappies*, conveniently storing them for fewer trips to the bin. When the bin is full, simply cut the film and tie a knot in the end. The refills will wrap approximately 66 nappies*. When you come the end of a refill, simply place a new refill cassette in the bin with a knot tied in the end.
