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 Jason Fanney

I purchased two of these. One in this blue color and the other in the green . Sometimes I take several mile walks (six miles and over) and I wanted a way to carry various nuts, veggies, and other snacks in a water bottle pocket of my backpack in case I get hungry or need "fuel” to continue.The caps seal well (enough to hold liquid without leaks). The containers can be reconfigured (except for the bottom one) and stacked in a different order than size order. Also, I can use the entire stack or just one or two of the containers as the loop cap screws onto any top container in the stack.I wash these by hand although it says top dishwasher safe. There is a lot to wash because it disassembles into nine pieces including lids and loop cap that can be hooked onto a bag or belt loop (hook not included) or just carried by two fingers. Also, it is BPA free.The two negatives for me is that the caps screw on so tight I had trouble getting a couple of them unscrewed. Also, the circumference of the containers is similar to a large water bottle and will not fit in all water bottle holders.Seleware was established in 2006 in Dongguan in Guangdong, China and that is where these are made.
