DWËLLZA KITCHEN Push-Ring Canisters, Set of 6 at 1 Litre, Black Lids

Six boxes of one litre — 0.9 quarts, or 4.2 cups — measuring 5.2 by 3.8 inches at the base. Height is quoted twice: 6.2 inches in the specification and 6.25 in the description.

The lid seals by a ring you push down and lift to release, rather than a pump or a clip. One hand does it.

Lids are black with a white handle; bodies are clear.

Bodies wash in the machine; lids are best done by hand, and the seal itself should stay put. The maker also rules out boiling water.

The maker says the seal is tight enough for liquids. Set weight is given as 3 lb.
