Air seal - The multi-layer film in the cassette provides effective odour-barrier technology, for a more fragrant home. Easy to use and refill - All nappies in the nappy bin are safely contained and youll not have to touch or smell them ever again. Enviromentally friendly- As not all nappies are wrapped indivudally, the Mabel Home nappy disposal system uses up to 4 times less plastic.
