A squat jar means short, wide and stubby, with a mouth wide enough to get your whole hand in. The low centre of gravity keeps it steady on the bench, and the flatter height fits under low shelves where a taller jar won't. Same commercial grade glass as you'll find on supermarket shelves, and suitable for hot filling. Handy for anything you scoop rather than pour: cleaning paste, bicarb, washing soda, and just as at home in the pantry with honey or dips. Why it's on clearance Honest story, I ordered these by mistake. Good jar, not quite the shape I meant to buy, so they're going cheap and won't be restocked.
