Ideal size: screw caps made of metal fit jars and bottles with the thread diameter of 33 mm. These threads are common on mini jars and small bottles where you can make juice, jams, jams, liqueur or honey. Easy care: the screw lids are made of galvanised steel and covered with silicone inside. As a result, the contents will not react with metal and the lid will not rust. Food-safe: the preserving lids have three locking teeth and fit twist-off jars. They adapt well to the glasses, which guarantees successful mason jars. Airtight: curved twist-off lids are perfect for food preservation. The sunken lid guarantees a tight seal and protects the contents from air access. Versatile: the lids for screw jars are available in five colours: gold, red, black, green and white. There are packages of 10, 50, 100 and 200 pieces.
