Purchased this for the awesome design. As a mom on the go, this looked great for holding a pump at the top and bottles at the bottom. However, the cooler stunk when I opened the box— like a weird chemically smell. When I opened the lunch box itself, the smell was stronger and could be compared to a cigarette smell. Even after washing the inside multiple times the cooler still sinks of chemicals so therefore I cannot use it for my breast pump or milk bottles.See full review
