These 380ml Glass Jam Jars from Argon Tableware are perfect for storing homemade preserves, pickles, dressings, and more. Their classic octagonal shape adds vintage charm and character, while also allowing for easy stacking and preventing them from rolling off surfaces. Each jar comes with a green metal screw-top lid that creates an airtight seal to help keep contents fresher for longer. Please note: Jars should be sterilised before use.
