This Kilner Screw Top Preserve Jar will keep your jams, jellies and chutneys fresh and tasty for longer! The easy to use lid is made up of 2 pieces – a replaceable vacuum seal and a metal screw band to secure the seal. The screw band can be used up to 10 times before being replaced, however the vacumm rubber seal will need to be replaced after each use. The Kilner brand is embossed on the front of the glass jar. Preserving is an economic and environmentally friendly way of maximising your fruit and vegetable stocks.
