ComSaf 1 Gallon Wide-Mouth Mason Jars 2-Pack — 128 oz Glass Storage with Airtight Lids & Writable Labels

These ComSaf 128 oz wide-mouth mason jars are one-gallon glass storage jars with airtight one-piece lids, sold as a 2-pack for large-batch pantry, fermentation, and bulk food storage.

If you store bulk ingredients, make large-batch recipes, or ferment at home, choosing the right jar matters. The ComSaf 1 gallon glass jars give you clear, durable containers with a 3.9-inch wide opening that simplifies filling, scooping, and cleaning. Each set includes two glass jars, two airtight lids, and two black writable labels so you can organize staples, starters, and prepared mixes without guessing what’s inside.

How do these jars make large-batch storage easier?

The 128 oz capacity holds bigger quantities of dry goods or brined vegetables so you refill less often. The wide mouth lets you add oversized items—whole cucumbers for pickling or large fruit pieces for sun tea—without wrestling them in.

• 1 gallon (128 oz) capacity for rice, flour, sugar, pasta, and more
• 3.9-inch opening accommodates large utensils and ingredients
• Smooth glass sides let you visually check levels at a glance
• Comes with two writable black labels for quick identification

Can these jars be used for fermentation, and how do the lids perform?

The jars are suitable for home fermentation projects, kombucha batches, and brined vegetables when you follow proper fermentation steps. The one-piece lids create an everyday airtight seal to protect dry goods and prepared foods; they are not meant for vacuum commercial sealing.

• Airtight one-piece lids to reduce air exposure during storage
• Use recommended fermentation practices—burping and weight methods—if fermenting
• Not designed for professional vacuum sealing or pressure canning
• Dry lids after washing to maintain the seal and avoid rusting under moisture

What cleaning and care should I follow for these large glass jars?

Because they are tall and roomy, dishwasher fit varies by machine and rack layout; many users prefer hand washing for convenience. Avoid rapid temperature shifts—don’t move a cold jar directly into boiling water—so the glass stays intact and safe for repeated use.

• Hand washing recommended for easier access and to protect lids
• Dishwasher possible depending on your rack space; check fit first
• Let lids dry fully before storing to prevent moisture-related issues
• Avoid sudden temperature changes to reduce thermal stress on glass

How will these jars fit into my kitchen organization routine?

The clear glass and smooth sides make contents instantly visible, and included black labels let you track dates, batches, or contents. Their size is ideal for top-shelf pantry storage, countertop display for frequently used staples, or as staging jars for meal prep.

• See contents at a glance—no measuring marks included
• Use labels for date, content, or batch notes to simplify rotation
• Stackable in concept but consider weight and shelf strength before stacking
• Versatile for dry goods, starters, kombucha, sun tea, and bulk items

Who is this for: Home cooks, fermenters, and anyone stocking a high-use pantry who needs roomy, clear storage that’s simple to fill and clean. The ComSaf 1 gallon jars suit households preparing large recipes, storing bulk dry goods, maintaining sourdough or kombucha starters, or anyone who prefers visible organization with reusable airtight lids.
