Yes, these are it! These really are leakproof!!! Filled one with water and shook several times and not a drop came out. Nicely lightweight - about the weight of store-brand tupperware containers. Had bought two other varieties of SS containers and both had raw exposed edges and these ones have nice, rolled edges with no raw material showing through. Excellent design and I feel safe to store my toddler's food in them.
Edit: Have used these almost daily for the last few weeks and so far no complaints. They indeed are leakproof. Noticed a metallic taste to greek yogurt after storing for maybe two hours, but perhaps that is to be expected given that acidic foods will acquire a metallic taste from stainless steel.
Edit 2: Now almost a year after purchasing and daily use, I have not had the metallic taste reoccur after that first time, despite still storing frozen blueberries or raspberries with yogurt all the time (a rather acidic mixture). My toddler has dropped these many times and they are still perfectly dent-less. And I've never had a leak. I am now buying a second set because we use these so much. I have also become much more savvy about SS products, and love that these are a very high grade of stainless steel (i.e. will not rust).
