Review on SELEWARE Portable Stackable Food Storage Containers For Snacks Formula Powder And Drinks Twist Lock System Airtight Leak-Proof BPA And Phthalate Free Blue Green And Orange by Michael Richardson

This is great for kids snack. Portion size and ease of carrying. But it's one of those containers where it has grooves? Indents? not sure what to call them on both sides so putting it in the dishwasher you have to drain the water from the top. I can understand the lids because it has to accommodate both top and bottom but don't understand why they had to make the containers concave on the bottom if it was flat it would have been better. Otherwise it's been great but once your kids drops them I can see it cracking. It's like those acrylic containers that's stiff and not the tupperware kind.
