For small caps: screw caps made of metal fit jars and bottles with a thread diameter of 38 mm. These threads are common with mini glasses and small bottles. (in which you can store juice, jams, fruit brandy or honey.) Easy care: the screw lids are made of galvanised steel and covered with silicone inside, which is safe in contact with food. As a result, the contents will not react with metal and the lid will not rust. Reliable closure: the canning lids have three locking teeth and fit twist-off jars. These are reliable fasteners that allow safe sterilisation of the preserve. They adapt well to the glasses. (which guarantees successful preserving jars with fruit and vegetables as well as alcoholics.) Airtight: curved twist-off lids are perfect for pasteurisation. The sunken lid guarantees a tight seal and protects the contents from air access, drying, moisture and dirt. Versatile: the lids for screw jars are available in six colours: silver, red, green, gold, black and white. There are packages of 10, 50, 100 and 200 pieces. This allows you to adjust the colour and quantity to suit your needs.
