This special jar opener quickly and easily grips lids ranging from 2.5-9 cm in diameter. Traditional crown caps and small screwtops can be opened with the small eye. For aufreiss-style lids, the end of the opener is pressed against the fastened jar, and the bracket is lifted. Finally, simply twist the plastic lid anticlockwise to open the screw caps. Cleaning is easy - all you need to do is wipe it with a dry towel.
