I always get tired of trying to keep my nice plastic containers and lids together. As soon as Ziploc started selling disposable containers I was immediately sold. Recently, I purchased Ziploc's 2 Pack of Large Rectangle Disposable Containers. My son was having a party at school and I was in charge of making cupcakes for the whole class. I did not want to use my nice containers because I was not sure if I would get all the pieces back so I went to our local Walmart and saw the large rectangle disposable containers. Since I put the cupcakes in these containers, I told the teacher to just throw them away when the class was done. These containers are also great for storing left overs. You can see easily what is in each container. The containers are mirowave, freezer and dishwasher safe.
