Ideal size: screw caps made of metal fit jars and bottles with a thread diameter of 33 mm. These threads are common for mini jars and small bottles where you can make juice, jams, jams, liqueurs or honey. Easy care: the screw lids are made of galvanised steel and covered inside with silicone. As a result, the contents do 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 preserving jars. Airtight: curved twist-off lids are perfect for food preservation. The recessed 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 packs of 10, 50, 100 and 200 each.
