1 Gallon Square Wide-Mouth Glass Jars 2 Pack - Airtight Storage

In this review of the 2 Pack 1 Gallon Square Super Wide-Mouth Glass Jars, the bottom line is simple: these jars are best for home cooks and bakers who need durable, large-capacity storage that keeps dry goods and liquids fresh. The reviewer found the standout feature to be the large capacity and thick glass construction, which makes them practical for bulk flour, sugar, pickling, fermenting, and visible countertop storage. The square shape also helps save cabinet space while the hinged, silicone-gasket lid delivers a reliable seal for both dry and liquid contents.

Key Features

• Large capacity: Each 1 gallon jar (about 4200 ml) holds large amounts of flour, sugar, or other staples so you can store in bulk and reduce refills.
• Wide mouth: The 4.3 in opening fits a measuring cup or large utensils easily, making scooping and filling quick and mess free.
• Airtight lid: The hinged lid with silicone gasket creates a double seal that helps keep dry goods fresh and prevents liquid overflow.
• Thick, sturdy glass: Heavier than typical pickle jars, the thicker glass feels durable and stands up to regular kitchen use.
• Space-saving square body: The square shape nests cleanly on shelves for more efficient storage than round jars of the same volume.
• Extras included: Two extra silicone gaskets and chalkboard stickers are provided to extend use and aid labeling.

Who It's For

These jars suit home cooks, bakers, and anyone who stores large quantities of dry goods or brined items. The wide mouth and large volume make them ideal for measuring and scooping flour, sugar, oats, or pickles, and the airtight seal is useful for fermenting small batches.

They are less appropriate for users who need compact single-serving containers or lightweight travel jars, and those who prefer plastic containers for extreme drop resistance should look elsewhere.

Pros & Cons
