Orderly storage is critical for any small space. And we here at Big City, Little Kitchen prefer storing and reheating in glass containers, instead of plastic. That makes the Glasslock 18-Piece container set a surefire hit for sure thanks to a reasonable price, over-safety, microwave-safety (remove the lid first!) and high-quality lids. Also the rectangle design is much more space efficient than circular containers, so you can maximize the volume of your fridge and cabinets.
