The OOTS! latest product line consists of cool, contemporary lunch boxes. Cleaning is easy and the use of space is optimal with custom containers that comfortably fit inside. The lid of the box is shaped to keep a bottle in place under an elastic strap. All materials used are food safe and kid-friendly: made from BPA-free and phthalate-free polypropylene and safety tested for lead. The lunch box and containers are dishwasher safe (top rack) and the containers can be used in a microwave. The ‘stacked’ design and materials used give these lunch boxes a surprising look and make them playful and tactile objects for little fingers. The upright design also prevents food from being tossed around. Great for grown-ups too!
