I am actually not sure how I'm going to use these. The serving size may be too big for soup, although I read somewhere not to fill containers completely full because the food might expand and burst the container. I was also thinking these could hold smoothies or fruits and berries. I got them to complete the set as I also purchased the 8 oz. and 16 oz. versions. Either way, I think these will somehow come in handy as I meal prep for five days worth of food for my husband and I to take to work. Not sure how I am going to fit these into my lunch bag, but I will figure it out.
I love the quality and sturdy, screw on caps. No more spills.
