I send my son’s lunch to school to I needed some to put peanut butter, Nutella, etc in. This was a good option. It holds a good portion size. It is not leak proof however. If the lunch bag is going to be tossed around, I wouldn’t recommend putting anything liquid in there such as ranch.These are good to go cups. I use them for applesauce mainly. They generally don't leak. When I've had trouble with leaks it's turned out that 2 lids were stuck together and so it didn't flex right. I now check and pull them apart.These little plastic containers with lids come in handy for anything..I use them in the kitchen for little leftover chopped onion, to serve individual honey for dipping, and use for small dollhouse items, keeps little things in tact…I use thes foe hummingbird feeders. They absolutely love them.Perfect for my lunch salad dressings.Made a bunch of Jell-O shots for a party. They came out great! Great size and spill proof. Sturdy enough tooThey are exactly what i was expecting.Tienes la porción ideal para aderezarLlego en tiempo , buen empacado y es de la calidad que esperabaBuen tamaño y calidad, da presentación en comida para llevar
