Fyrkantig glasburk med klipplock - 1 liter

The clips snap shut with a satisfying click and the seal is genuinely airtight — I've had pickled onions in this for three weeks and the brine hasn't lost a drop. The square shape means it stacks neatly on my pantry shelf, which is a bonus over the round jars I used to wrestle with.

My chutney batch fit perfectly and the clip top sealed so tightly I could hear the satisfying pop as it cooled. The square shape means it stacks neatly in my pantry, saving a lot of shelf space.

The clip top seals with a satisfying pop, and the glass feels thick enough to survive my clumsy hands in the kitchen. Made three batches of chutney this weekend and not a single leak.
