Thanks for the response! Just a few points of clarification...ReUsies are lined with a leak-resistant nylon (not vinyl) that is Lead, BPA, and Phthalate Free. Our kids were smaller when our company started and while older kids and adults can use storage containers, it was a problem for little kids to open and close. ReUsies definately fit a need for the smaller kids, and now because of their packability and compact nature people are using them because they're not as bulky. We love that everyone is doing what they can to eliminate waste! This is just one of many options out there to choose from.
