Square glass jars are a step away from the conventional round jam jar that still gives you the perfect opportunity to store your jams, chutneys, marmalade thanks to the high quality round jars we provide in a range of sizes. Our square jars come complete with lids in a choice of different colours that all perform the same crucial function of having an integral acid and vinegar proof seal. The height of the square jars both with and without lids are presented plainly and you can select a sample before you buy, or you can choose the quantity pack that is right for you.
