These are mediuam size containers we were looking for. Love the storage for refrigerators and we were able to stack two on top of one another in the fridge. Have been wanting to get rid of some plastic containers for a while. Got some of these and it is working great for us. From reading blogs, it is better NOT to put the lid in the dishwasher. I have not tried it and will not try it. The glass container can take anything you throw at it... Love this product!
