DII Silicone Collapsible Airtight Food Storage Containers (Set of 2). I took these along with us to try them out traveling. Other than being sent the two containers for free in exchange for an honest review on Amazon, I received no other form of compensation. In fact, this review is a bonus for them and you!
I used them to pack away snacks for the long trip such as these milk chocolate covered raisins for my husband. The size and same of the container allowed him to just rest it between his legs on his seat so he could just reach down and snag a snack when it wanted it. The softness of the silicone didn't hurt him as hard plastic containers have in the past. However the container is firm enough that he didn't have to worry about the treats spilling out as he has with bags.
I also used these containers to store some of the treats I bought at shop so that they would not get damaged and we could eat them later. You don't need to eat every part of a bar or bag of candy or chocolate but often I think we do when we travel simply because it is a challenge to store them where they will not break or melt.
