- Brand: POLBAN - Item: Hip seat body + single shoulder - Color: Navy - Age range: 7-36 months Can be used by both mom and dad. It was useful when the child started walking and for carrying. I used it from when my child started walking until they were about 2 years old, but I didn't use it that often because my child often asked for a baby carrier, so there isn't any noticeable dirt. The box and instruction manual will be included. POLBAN Lucky Industry
