This is my favorite new casserole pan. It is compact, holds cakes, brownies, leftovers, etc., without things, getting squished. It is stackable and compact for easy storage in the refrigerator or in the kitchen when not in use too! Easy to clean :) and dishwasher safe! I love these more than my glass pans and will probably buy more in the future for freezer meals and frozen to go desserts to bring to family parties. I ordered 2 packs, so 4 altogether and have considered getting rid of the glass containers I used to use. I love how light these are too.
