Reading is even more fun and interactive with the Miffy and melanie hand puppets. This set consists of one Miffy hand puppet and one melanie hand puppet. Proceeds from the sale will go to sickle cell disease. Sickle cell disease is the most common hereditary blood disorder in the world. It is accompanied by severe pain attacks. Without treatment, 75% of children do not live to be older than 5 years. Yet this disease is unknown to many people. That is why Miffy has become an ambassador for the Sickle Cell Fund, with the aim of drawing more attention to this disease and raising money for research into its treatment. Because sickle cell disease is too painful not to know.
