I can’t say enough about how amazing these are. I ordered these to replace the gogurts in my kids lunches and they love these so much more. I haven’t had issues with any of them leaking, there is an easy to read fill line, and it comes with a funnel. I make pineapple flavors, strawberry banana, even s’mores...and they are all natural and vegan most of the time. I feel much better controlling the ingredients, definitely an awesome product!
