The Dr. Doll is made of safe, durable, non-toxic, odorless and BPA free acrylonitrile butadiene styrene plastic. The doll is generally soft and has no sharp edges, so you don't have to worry about hurting the children themselves while playing. The doll's limbs can be rotated flexibly, which is more interesting and easier to interest children. It helps to exercise the flexibility of children's hands, stimulate their imagination and creativity.
