Review on Set Of 4 Blue Round Collapsible Silicone Food Storage Containers With Airtight Lids And Air Vents - Ideal For Meal Prep, Leftovers, Freezing, Microwaving, And Dishwashing - 16.9 Oz Capacity by Cindy Carlin

Overall I like these containers and the customer service is great. I purchased them to send snacks to daycare with my toddler. The size is right. We use them fully open and at the collpased size. They are lightweight.However, they are not great quality. The first set I got the plug on the top the lid of one was broken. Given these are for a toddler it is a choking hazard. This is where customer service was responsive and I got an entire replacement pack. In that pack three out of the four lids had defective plugs. These containers do what they claim to, they are just inexpensively made.
