I can’t say enough good things about not only these containers but the company and customer service too! The containers are great quality. The kids fit great and remain airtight. GREAT VALUE FOR YOUR DOLLAR. We looked at several containers online and thought these were the best value. We were a little worried about what we would get but figured we could return them if we didn’t like them. Boy, what a pleasant surprise! These containers are a good thickness and the sizes are perfect. We love them. MOST IMPORTANTLY, this company’s customer service is off the chart!! They say they pride themselves on their customer service and THEY MEAN IT! Once we ordered we received a message from the Co-Founder ensuring everything was good and we loved our containers. When we replied back with questions, he promptly replied, answered our questions. There was some confusion and I thought we didn’t get what we ordered because my wife ran off with containers right away. The Co-Founder went above and beyond to ensure our satisfaction - both before and after I discovered there truly wasn’t a problem. This company’s home page of their website has a place to send them messages. No digging through pages or searching for contact information, their contact info is right there like they welcome your comments. Many companies could take a lesson in customer service from them. I highly recommend their products!
