UrSpeedtekLive 40 Pack 4 oz Mason Jars — Small Canning Jars with Lids, Food-Safe Glass & Labels

These are 40 small, 4-ounce glass mason jars by UrSpeedtekLive with screw bands and flat lids, designed for safe food storage, canning, crafts, and gifting.

Whether you're preserving a small batch of jam, packaging party favors, or organizing spices, this bulk set offers uniform, food-safe containers that balance compact size with reliable sealing. The jars are crafted from high-visibility, BPA- and lead-free glass and include split-type metal lids to form a tight barrier against air and moisture. The kit also comes with labeling stickers and decorative string so you can package and identify contents quickly.

How do these jars keep food fresh?

The included flat lids and screw bands create a split-style sealing system: the metal disc seals against the rim while the band holds it in place. That configuration helps reduce air exchange and moisture intrusion for short- to medium-term storage. Jars are reusable and the glass resists stains and odors after cleaning.

• Flat metal discs with sealing layer to reduce leaks.
• Screw bands clamp lids tightly during storage and transport.
• Glass body prevents staining and holds visibility for contents.

Can I use these jars in the dishwasher, microwave, or fridge?

The glass jars are dishwasher-safe and fridge-friendly, making them practical for everyday kitchen use. You can microwave the jar body on its own, but remove the metal lid first because metal should not go in the microwave. Bands and lids should be hand-washed to preserve their sealing layer and finish.

• Dishwasher safe: glass only; remove lids before cycling.
• Microwave safe: jar body only; lids must be removed.
• Refrigerator safe for chilled storage and single-serve portions.

What are the jars best used for beyond canning?

Their 4-ounce capacity and neat silhouette make these jars versatile for food and non-food projects. Use them for spice organization, single-serve desserts, DIY candles, or small craft supplies. The included labels and twine help convert the set into ready-to-give favors or neatly organized pantry items.

• Portioning: sauces, dressings, overnight oats, condiments.
• Gifts: wedding favors, shower gifts, homemade candles or candies.
• Organization: spices, seeds, craft beads, office supplies.

How many pieces come in the package and what extras are included?

The set contains forty 4-ounce glass jars plus split-type metal lids and screw bands. It also includes 42 adhesive labels for marking contents and two bundles of decorative string for tying tags or creating a finished look. All pieces are packed in protective foam to reduce shipping damage.

• 40 glass jars (4 oz each) with silver metal lids and bands.
• 42 writable labels for easy content identification.
• 2 bundles of string and foam tray packaging for protection.
