Twist and shout with joy. A new era in lids has arrived. By combining advanced technology and a refusal to accept the status quo, a new generation of lids has been born. Our revolutionary design simply requires a light button push to release the vacuum from the container, making the closure a snap to remove. After releasing the vacuum, an individual can reset the button by simply pressing on the bottom/product side of the button for storage of any remaining product. That means ensuring freshness has never been easier either.
