Square Super Wide Mouth Airtight Glass Storage Jars 2 Pack - Large

In this review of the 2 pack Square Super Wide Mouth Airtight Glass Storage Jars, the bottom line is simple: these jars are best for home cooks and bakers who need large, stable containers that are easy to fill and measure. The single biggest reason to buy is the super wide 4.3in mouth combined with clear tick marks, which makes transferring, scooping and portioning dry goods or liquids faster and less messy than with narrow-neck jars.

Key Features

• Super wide mouth: A 4.3in opening lets a 1 cup measure fit easily and makes it simple to reach in for scooping or cleaning.
• Dual measurement marks: Fluid ounce and millimeter tick marks on the glass remove the need for a separate measuring cup for many tasks.
• Airtight leak-proof lid: The hinged lid and silicone gasket form a double seal to keep dry goods fresh and prevent spills.
• Thickened glass: Heavier-than-normal glass walls increase durability and stability on shelves and countertops.
• Space-saving square shape: A 4200ml capacity in a compact 10in by 5.1in footprint fits neatly on pantry shelves and counters.
• Extras included: Each package includes spare silicone gaskets, stickers and a marker for labeling.

Who It's For

These jars suit home bakers, cooks, and anyone who stores bulk dry goods such as flour, sugar, oats, coffee, or snacks and wants easy access and built-in measuring. The wide mouth and square profile make them especially useful for frequent use on the countertop or pantry where scooping and portioning are routine.

They are less appropriate for users who require tempered, oven-safe glass or need lightweight travel containers; also those who frequently expose containers to sudden temperature changes should follow the anti-crack guidance to avoid damage.

Pros & Cons

Pros

• Very easy access thanks to the 4.3in wide mouth, which speeds filling and cleaning.
• Clear tick marks provide convenient in-glass measuring for many recipes and liquids.
• Hinged lid with silicone gasket gives a reliable double seal for dry food storage.

Cons

• Some customers report mixed durability; thick glass is heavier but can still be brittle if subjected to impact.
• The jars require care with temperature changes and a warm-up step before adding very hot liquid.

Frequently Asked Questions

Can the tick marks replace a measuring cup?
Yes, the jars have fluid ounce and millimeter marks that allow quick measuring of many liquids and bulk ingredients without a separate cup.

Are the lids fully leak-proof for liquids?
The hinged lid and silicone gasket form a double seal that prevents most leaks, but users should ensure the gasket is seated properly and avoid dramatic temperature changes when filled with hot liquids.

What should I do to avoid cracking?
Soak jars with lids in warm water before pouring in boiling water and avoid sudden temperature changes or placing hot jars on cold or wet surfaces.
