Ball® Sure Tight® Band Tool for Mason Jars
Secure jar bands with confidence! The Sure Tight™ Band Tool secures jar bands with the exact right amount of torque. No worries about it being too loose or too tight. Also use the lid-open function to unscrew the band. The uncapper device at the end even helps you pop the lid off.
Getting a good seal starts with securing the band with the correct force. This tool takes the guesswork out of securing the band to “fingertip tight”.
