PINIWON 4 oz Mason Jars 40-Pack — Clear Mini Canning Jars with Silver Airtight Lids & Seals

PINIWON 4 oz mason jars are a 40-piece set of small, food-safe glass jars with airtight split-type lids, designed for pantry storage, gifts, and DIY projects.

These compact 120 ml jars combine clear, durable glass with silver lids and silicone sealing rings to keep small-batch foods and handmade goods tidy and visible. The package includes 40 jars, 90 adhesive labels, and two bundles of string, all wrapped with foam protection for safe delivery. Built for everyday use, they’re dishwasher safe, microwave safe without lids, and refrigerator safe — making them a flexible option for home canning, organizing, and gifting.

How do these jars keep contents fresh and spill-free?

The set uses split-type metal lids paired with silicone sealing rings to form a close-fitting barrier that minimizes exposure to air and moisture. While not intended for long-term commercial canning under pressure, the combination reliably reduces leaks for sauces, jams, and cosmetics when stored upright.

• Silver split-type lids with replaceable silicone sealing rings for a snug fit
• Airtight and leak-resistant for upright storage and transport
• Recommended to dry lids after washing to prevent rust and preserve seals

What practical uses do 4 oz jars have around the home and events?

At 120 ml capacity, these mini mason jars are sized for single-serve condiments, sample-sized skincare, or small crafts. Their transparent walls make contents instantly identifiable, and included labels and strings let you personalize jars for parties, weddings, or product samples.

• Portioning jams, honey, sauces, spices, and candy
• Packaging bath salts, sugar scrubs, candles, and body butter
• Wedding favors, baby showers, craft kits, and small gift packaging

Are these jars durable and easy to clean?

Each jar is made from food-grade glass that’s BPA- and lead-free for safe contact with consumables. The glass construction resists staining and odor retention, while the jars themselves are dishwasher safe; remove lids before microwaving to avoid metal exposure.

• Food-grade, BPA-free and lead-free glass construction
• Transparent walls for visible contents and easy monitoring
• Dishwasher safe; microwave safe without lids; refrigerate as needed
