ive been using flat stacks for about 3 years and love the product. When I had a question about placing a special order they called me back and solved my issue!
I have these containers and I love them, if I have a small amount left over after a meal I put it in one of the smallest ones and collapse it, you have a choice of different sizes for large amounts or smaller amounts.
The item for storage purposes is good, but doesn’t have a solid seal so dies leak some when traveling. Mostly a problem when taking left overs for lunch.
