ComSaf Square Glass Clamp-Top Jars with Chalkboard Labels, 51 oz Each, Set of 3

Three square glass canisters that line up edge to edge, so a row of them wastes less shelf depth than round jars of similar volume. Each holds 51 oz (about 1.5 L) and closes under a hinged wire clamp seated on a silicone gasket.

• Format: a square profile 4.4 in wide and 7.7 in tall, with an opening broad enough to admit a scoop or a hand.
• Closure: a metal wire clamp working against a silicone gasket ring; ComSaf positions the seal for fermenting projects such as sauerkraut or kombucha.
• Body: clear lead-free glass, so stock levels read from outside.
• Included: three jars plus a sheet of write-on, wipe-off labels.

Care: the jars themselves can go through a dishwasher; wash the clamp hardware and gasket by hand.

One figure in the supplier data needs care: the 2370 g weight sits in a per-item field but corresponds to all three jars together, so it is a packed set weight rather than the mass of one canister. The 25 per cent space saving quoted in the original copy is an unsupported marketing figure and is left out here.
