[ULTRA-FRESH!] The Turn-N-Seal containers prevent both air and moisture from getting access to the food stored inside, keeping food fresh and vegetables crisp. Most importantly, the vacuum could prevent Ochratoxin A from growing, not only preserving the flavor but also keeping you healthy. [Easy to use!] Turn-N-Seal is a new approach to perishable food storage that uses a powerful but simple-to-activate vacuum airtight seal. Unlike other vacuum seal systems on the market, Turn-N-Seal's special lids pull all the air from each container with a mere flick of the wrist. [AWARD-WINNING AND SAFE!] 100 percent leak and odor proof. BPA-free materials used in construction. Winner of 2016 iF Design Award and the 2016 Red Dot Design Award. [ALL KINDS OF STORAGE!] Turn-N-Seal is also useful for perishables that require peak freshness to retain their quality: like newly picked herbs, ground coffee, whole coffee beans, or teas.
