Kilner Rubber Seals are suitable to use with the Round Clip Top Glass Storage Jars. Pack of 6 These replacement seals can fit 0.35, 0.5, 1, 1.5 and 2 Litre Jars. These come in a little plastic bag, not what we would usually accept at AnniePooh but as they will prolong the life of your Kilner jars I decided it’s for the greater good!
