Extra Large Square Glass Flour & Sugar Storage Containers - Airtight 2

Our review of these extra large square glass storage containers finds them best suited to home cooks and bakers who need bulk dry goods storage with clear visibility and a solid aesthetic. The single biggest reason to consider them is capacity: the two 168oz jars hold up to 10 lbs each and have a 6in wide mouth that makes scooping and refilling easy. In use they combine thick borosilicate glass with bamboo lids and silicone seals for a modern pantry look and generally dependable airtight performance.

Key Features

• Extra large capacity: Each jar holds up to 168oz, making them practical for storing flour, sugar, rice or cereal and reducing the need for frequent refills.
• Wide mouth design: The 6in opening allows a one-cup scoop to be removed easily and simplifies refilling without spills.
• Thick borosilicate glass: At about 3mm thickness the glass is designed to be dishwasher and fridge safe and resists thermal shock across normal kitchen temperatures.
• Airtight bamboo lids: Natural bamboo lids with food-grade silicone rings help keep contents dry and deter ants when the seal works as intended.
• Stackable square shape: The square profile saves pantry space and lets jars line up neatly or stack when needed.
• Label kit included: A set of 72 kitchen labels and an erasable pen make it simple to identify contents and update markings over time.

Who It's For

These glass jars are ideal for households that buy staples in bulk and want durable, clear storage that looks tidy on open shelves or in a pantry. Bakers and anyone who measures by cup will appreciate the wide mouth and the ability to store roughly 10 lbs of flour or sugar per jar.

They are less appropriate for someone who needs indestructible, lightweight containers for travel or rough handling, since some customers report breakage and mixed experiences with the airtight seal. If an unbreakable plastic option is required, consider a different material.

Pros & Cons

Pros

• Large capacity and wide mouth make scooping and refilling simple.
• Attractive clear glass with bamboo lids improves pantry organization and visibility.
• Dishwasher and fridge safe borosilicate glass provides safer, long-term food storage than single-use plastics.
• Label stickers and erasable pen included for easy identification.

Cons

• Some users report inconsistent airtight performance from the lids; seals work well for many but not all jars.
• Glass can break if dropped, so these require careful handling compared with plastic canisters.
