I can’t believe these come with a California cancer warning for the materials used to make them when it’s a food storage container. We will be returning them. Very disappointed.
No, I would not recommend this to a friend.

Hi Robert,
Thank you for your feedback.
We're unhappy to read the California cancer warning on the food storage container has left you concerned. We completely understand why seeing a warning like that on a product intended for food storage would be unsettling. California's warning system relates to potential exposure to a listed chemical and does not automatically mean the container is unsafe or that it contains a cancer-causing substance at a harmful level. That said, we understand your concerns and appreciate you sharing them with us. We've noted your feedback and will share it with our product development team for future consideration. Should you require any support, feel free to reach us using the link below. We're here to help.
Found the coupon for these 2 extra pint containers w/ lids. Have been great because now I can have a more varied flavor selection. Thinking about getting even more!
I saw such a difference between the brand name Ninja containers as opposed to the generic containers. These tops didn’t warp, the containers clean out easily, and they are terrific to allow me to freeze 8 containers at once. Yummy treats of just-fruit sorbets!
