Featuring two knitted uterus models and a fetal model with brown skin tone, this versatile childbirth teaching set is great for demonstrating what happens during effacement and dilation. The set’s Knitted Uterus/Vagina Model and Cesarean Version Model are made of variegated blue acrylic yarns that differentiate the fundus, lower segment, cervix, and vagina (attached with snaps). The Cesarean Version also has a low-transverse zippered opening. Each uterus model is approximately 14" x 9". The included Fetal Model, Brown, measures 17½" long.
