This is a review coming from Naturally Trendy. They are a eco friendly baby boutique and carry all of your babies needs. They sent me their large stainless steel snack container which retails for $6.95.
Finally  there is stainless steel snack container for our children!  Put away the  plastics and go with stainless. Lightweight and sleek, this snack container can  be used for storing baby food such as puree, cereals, or fruits. No more baby  food tasting like plastics! Small enough to fit nicely in your diaper bag for  to-go snacks. This container can be used even beyond baby years. You can store  dressings, soup, nuts and anything else you might like on the side. While it is  not leak proof, it is water-resistant.  As long as the carrier is not  aggressively shaken or flipped upside down, it usually holds  liquids well. 
The  stainless is 200 grade, a grade specifically made for safe storage of food  stuffs.  300 and 200 are the most popular, with 200 containing less nickel than  200.  Lab tests have shown that our stainless steel contains no levels of  materials harmful to people or the planet.
Due to the  nature of stainless steel, particularly the kind approved for food  storage, there is no coating on the stainless steel - that's why it's such a  popular material for kitchen, food and medical use.
Just like  any other steel and metal products, it is not safe for use in the  microwave.
