Question: Do the bowls nest for storage?
Document: These bowls are the  perfect  size for every event.
Love these bowls! So light weight and easy to use. Haven't tried hot food yet but keeps food cold nicely. Used at several picnics for items that has mayo as an ingredient.
It also makes the bowls NOT leak proof, so it must be kept upright to avoid spilling.I'll be keeping this to use for lunch, but I'll still keep an eye out for a better insulated bowl.
I love these bowls they work beautifully, I already used them at a party to serve hot food and it stayed hot for hours the bowls look good and the locking lids keeps it nice and tight , this is an excellent product and I highly recommend this
They do keep your food warm as long as you don't open the lid. Although I was a little disappointed on how the actual lid locks into the bowls. They are not meant to be used with soups or sauces, they will spill out. The lids lock into place with notches, so if you are looking for some that stays tightly shut, keep looking these are not like that.
I also wrap the whole thing in 2 layers of aluminum foil. After 4 to 5 hours, the food is still warm and edible without really needing reheating, but definitely not hot. I would't recommend this for foods that have a high risk of spoiling at warm to Luke warm temperatures, but it seems ok for foods that you can heat up to steaming temp first. Also, the bowls are really light and the lid turns only an inch or so into a notch to close.
i bough them for my daughter. she realy likes them. she takes meals to church and  nursing homes.and need to be keep warm.
Very good looking and light. Easily screws on to secure. Keeps hot 4-6 hours. Cannot put in microwave or oven to reheat. Bought it to be able to bring a whole meal cooked and warm to my mother who lives 45 minutes away. Perfect for that or to a pot luck party.
They're great!!! I would highly recommend to anyone that is considering it! And trust me, I cook a lot, so I can tell you from first hand experience, these are such a huge help! I have multiple sets and LOVE THEM!
They don't seal, so they aren't great for travel. I bought them to keep food warm I take to my Mom. Corning ware in an insulated food bag does almost as good and it is microwavable, and dishwasher safe.
Answer: Yes I have the bowls and they do nest for storage but with the lids off of course which need to be stored seperatly.
