Review on Sensory Baby Ball By Edushape - 7 Inch Transparent Primary Color Ball For Enhanced Gross Motor Skills Development In Infants 6 Months & Up - Vibrant Colorful & Textured Ball For Babies - Single Pack by Mdl Thurston

My daughter plays with these a lot while in daycare. So we bought them for her to play at home. We bought both the small and large size balls. The balls are a soft flexible plastic material. The spikes are perfect for teething and the texture helps her grab and hold on to the ball. They're easy to push and she smacks them around and crawls behind it to do it all over again. I gave it a 4 because the material is really soft and they deflate quicker than expected.
