Square Glass Jars with Airtight Lid Set of 3, 78 floz Wide

Product Overview

The Square Glass Jars with Airtight Lid Set of 3 is a thoughtfully designed kitchen essential that combines functionality, durability, and style. Perfect for modern homes, these wide-mouth glass containers are ideal for organizing and preserving dry pantry staples like flour, sugar, rice, cereals, pasta, beans, and more. Each jar holds approximately 78 fluid ounces—a generous capacity that supports both everyday use and meal prepping needs. Made from high-quality borosilicate glass, these jars are not only eco-friendly but also built to last. The included airtight clamp lids feature food-grade silicone seals, ensuring freshness by blocking out moisture, air, and pests. Whether you’re storing baking ingredients, fermenting vegetables, or canning preserves, this versatile set enhances both kitchen organization and food safety.

Key Features

• Large Capacity & Wide Mouth Design: Each jar offers about 78 fluid ounces of storage space with a 4.53-inch wide opening. This design allows for easy scooping, pouring, and refilling—ideal for handling bulk foods such as grains, legumes, and baking supplies without spillage.
• Airtight Clamp Lids with Silicone Seals: The stainless steel clamp lids come equipped with durable food-grade silicone rings that create a tight, leak-proof seal. This prevents oxidation, keeps odors at bay, and significantly extends the shelf life of stored items—making them perfect for long-term preservation of dry goods.
• Thick, Heat-Resistant Borosilicate Glass: Crafted from 6mm-thick borosilicate glass, these jars are scratch-free, BPA-free, and lead-free. They withstand extreme temperature changes from -4°F to 302°F, making them safe for use in freezers, refrigerators, microwaves, and dishwashers. Their thermal shock resistance reduces the risk of cracking during sudden temperature shifts.
• Clear Visibility & Transparent Texture: Thanks to the high-clarity borosilicate material, you can easily monitor your inventory at a glance. No more guessing how much flour or rice is left—this transparency helps reduce food waste and streamline meal planning.
• Eco-Friendly & Easy to Clean: Reusable and fully dishwasher-safe, these jars support sustainable living by reducing reliance on single-use plastics. The wide mouths simplify hand washing and allow for thorough cleaning, even of sticky residues.
• Comprehensive Labeling Kit Included: The set comes with 72 reusable labels: 54 pre-printed with common kitchen items (flour, salt, pasta, etc.), 18 black writable stickers, and one white erasable marker pen. This labeling system helps eliminate confusion between similar items—such as distinguishing regular pasta from gluten-free versions—and supports organized, clutter-free storage.
• Space-Saving Square Shape: Unlike traditional cylindrical mason jars, the square design maximizes vertical space in cabinets and countertops. It stacks neatly and presents a clean, modern aesthetic that fits seamlessly into any kitchen decor.

Benefits & Use Cases

This glass jar set is ideal for anyone aiming to improve kitchen organization, extend ingredient freshness, or adopt a zero-waste lifestyle. The airtight seal makes them suitable not only for dry goods like all-purpose flour, brown sugar, oats, quinoa, and gluten-free pasta but also for fermentation projects such as sauerkraut, pickling cucumbers, or storing homemade jams and preserves. Their stackable square shape ensures efficient use of cabinet or pantry space, outperforming round containers in storage density. The included labeling system further enhances usability by helping users quickly identify contents—reducing confusion and minimizing expired or forgotten items. Whether displayed on a countertop as part of a farmhouse-style kitchen or tucked away in a pantry, these jars add both practicality and visual appeal.

Important Notes

While these jars are highly durable, avoid placing hot glass directly into cold environments (like the freezer) to prevent thermal shock. Allow heated jars to cool gradually before refrigeration or freezing. Over time, the silicone sealing ring may develop slight discoloration when exposed to acidic foods, though this does not affect performance or safety. The water-resistant labels can be erased with a damp cloth; however, prolonged exposure to moisture may cause ink smudging. The set requires no assembly and is ready to use immediately upon delivery. The manufacturer stands behind product quality with a one-year after-sales service commitment, ensuring customer satisfaction and peace of mind.
