Accguan 4oz Mason Jars Set of 40 — Small Thick-Glass Canning Jars with Silver Stainless-Steel Lids for Spices, Jams & Gifts

Accguan 4oz mason jars are a 40-piece set of small, thick-glass canning jars with silver stainless-steel lids designed for preserving, portioning, gifting and small-batch crafts.

These compact 4-ounce jars combine sturdy, clear glass bodies with food-grade, silver-coated stainless-steel screw lids to give you reliable storage for jams, spices, condiments, and handmade goods. The set of 40 offers consistent sizing for batching, labeling and display, while the tight-threaded lids reduce spills and make the jars practical for refrigerator, pantry and market use.

How secure is the seal for liquids and sticky foods?

The lids feature precisely cut threads and a quality coating to create a tight closure that helps prevent leaks of honey, sauces and preserves. For longevity, hand-wash the lids and dry them promptly; the jars themselves are dishwasher-safe once lids are removed.

• Silver food-grade stainless-steel screw lids with sealed threading
• Recommended to hand-wash lids and remove before dishwashing or microwaving
• Clear glass bodies make it easy to inspect contents visually
• Thickened glass reduces the risk of breaking during everyday use

Can I use these jars for canning, heating or freezing?

The thick glass is safe for refrigerator storage and can tolerate everyday temperature changes, but avoid subjecting jars to sudden extreme temperature shifts. Lids should be removed before microwaving or heating; to protect the lid coating, dry metal parts immediately after washing.

• Microwave- and refrigerator-safe when lids are removed
• Avoid direct exposure to rapid temperature changes to prevent stress on glass
• Remove lids before heating to extend lid life and prevent coating wear
• Dishwasher-safe jar bodies; hand-wash lids for best results

What practical uses do these 4 oz jars have for home, craft or business?

These small mason jars work for a wide range of kitchen, beauty and craft needs: portioning preserves, storing spices or nuts, packaging small-batch condiments for farm markets, and creating candles or bath-salt gifts. Their uniform size makes them ideal for events, wedding favors, and product labeling for small businesses.

• Jams, sauces, honey, condiments and spice storage
• Portioning snacks, candies, cosmetics and travel toiletries
• DIY projects: candles, aromatherapy blends, soaps and bath salts
• Event favors, mini dessert jars, or small-batch packaging for markets

How durable and easy to clean are these jars?

The jars are made from thickened glass that withstands normal kitchen handling and cleans easily in a dishwasher when lids are removed. The stainless-steel lids have a protective coating to resist wear, but washing them by hand and drying promptly preserves the finish and threads.

• Thick glass resists chips under normal use and cleans well
• Jar bodies are dishwasher-safe without lids
• Hand-wash lids and dry to extend coating and prevent rusting
• Consistent dimensions simplify stacking, labeling and display
