Kilner® 0.5 Litre Preserve Jar

The two-piece lid is a game changer—the screw band holds the vacuum seal snugly so I can hear that satisfying pop when it's sealed properly. It’s the right size for jams and chutneys, and the glass feels sturdy enough for repeated use.

The vacuum seal clicks into place with a satisfying pop, and the screw band fits snugly without any wobble. I've used it three times for jam already, and the seal holds perfectly every time.

The two-piece lid is so much easier to handle than the one-piece bands I've used before—the metal screw band grips firmly while the vacuum seal does its job. Made a batch of raspberry jam and every jar sealed perfectly on the first try.
