BPS, BPA, PVC and Phthalate free as always! Our 12oz/350mL Thermal Food Containers are sleek, light weight and free of the bulky plastic other containers have. Keeping foods hot or cold for 6+ hours, they are perfect for your child_s lunchbox or even Mom and Dad! The fun designs compliment our bottle line and, like our bottles, they close tightly with a leak proof silicone seal and are virtually indestructible. The stroller pack or purse friendly size is perfect for little hands to hold and little fingers to snack from.
