Pack lunch? Keep your salads dry and your veggies crisp by packing dressings and sauces separately in these containers. The flexible, easy to remove lids offer a leak-resistant seal. Unlike other small containers, little fingers will be able to take these tops off, so no worries that your child can't open them without help. However, please do not toss these separately into a purse or backpack, as the lid could bump up against something and come off. Recommended for use inside a lunchbox. Our Mini-Dippers are designed to fit inside the large compartment of our EasyLunchboxes compartmentalized food container, or use separately inside any lunch box. You can even freeze home-made baby food portions in these handy containers. Also useful as little storage containers for craft items like beads or small hardware. This set of 8 containers comes with four different lid colors (2 of each). The bottoms are made of polypropylene (No.5). Lids are low-density polyethylene (No.4). NO BPA or phthalates. Sturdy and reusable, safe for fridge, freezer and dishwasher. NOT for use in microwave. Each container holds 2.5 fluid oz. When not in use, they nest to save space.
