this is a well made and high quality plastic with removable dividers to adjust the size of the compartments to what you are storing inside it. The only thing wrong for me is that it doesnt actually fit in my refrigerator front to back because it is so long. I will change my rating from 3 to 4 stars today because of  the quality of the product and the best of storage with its adjustability to a constantly changing environment and I have bought a lot of different plastics for storage all over my house so I have definitely seen the good, bad and ugly of this type of storage.
