Clear Plastic Containers

We tend to buy most stuff in bulk around the house...it's cheaper and goes much further than going to the store every other day. So I bought a box of Oatmeal (which the boys LOVE for breakfast) and poured the bags into my plastic container. Then I thought...how am I going to know how much to make. So I pulled out my dry erase maker and wrote on the container...I didn't use permanent because I don't always put the same cereal in the same container.
