Jars with airtight lids for freshness: Many jars have bamboo lids but not all can boast a rubber seal that's truly airtight. The satisfying "Pop" on opening tells you it has been hermetically sealed - something you'll find in the best kitchen canisters. Air and odors stay out completely! Borosilicate glass is versatile and easy to clean: Did you know that glass isn't just glass? Borosilicate glass (aka space shuttle glass) is designed to withstand temperature changes without breaking. Put these glass canisters (not lids) in the dishwasher, microwave, freezer, or fridge, worry-free! Wide mouth storage jars in 6 multi-use sizes: your set contains varied sizes for tidy pantry organization. And, they're all 4" wide for reaching inside easily with a scoop! Inspired by sleek elegance and clean lines, a minimalistic design offers effortless luxury with monochromatic tones and bold, angular structures. Its unique profile will make an excellent addition to your living room, dining room, or bedroom in your modern home.
