The Kilner preserve jar is perfect for storing and preserving healthy, homegrown foods. Featuring a lid system that comprises a tin disc and screw band ensuring a secure vacuum seal is achieved, keeping the contents fresher for longer. The jar capacity is the perfect size for making jams, chutneys and small pickled fruits. Each jar embodies the traditional Kilner styling with the authentic embossed logo and contains a detailed instruction leaflet inside. Each jar is made from high-quality soda-lime glass material with pristine clarity and consistent wall thickness ensuring no weak points. The glass jar is dishwasher safe. The disc and screw band should be hand washed only and dried immediately. Glass is best for storing/preserving and transporting food and drink. It is made from natural ingredients so no harmful chemicals or toxins can leak into the food. Glass is BPA free and does not absorb odours, flavours or stains. Not only is glass a healthier option, but it is also made to last and never for single use. Kilner continues to tackle plastic waste with our ethos of reuse, refill, and recycle.
