Coloch 4 oz Mason Spice Jars 30-Pack — Clear Glass Mini Jars with Airtight Metal Caps & Shaker Lids

Coloch 30-pack 4 oz glass mason spice jars are compact, reusable glass containers with two-in-one shaker lids, airtight metal caps, and a collapsible funnel for clean, organized spice storage.

These mini mason jars give you a tidy, consistent solution for storing herbs, seasonings, baking supplies, and small craft items. Each 4 oz jar is made from clear, food-grade glass and fits neatly on spice racks, drawer organizers, or travel kits. The set includes 30 jars, matching airtight metal caps with removable shaker inserts, labeled stickers, and a silicone collapsible funnel to refill jars without spills.

How do these jars keep spices fresh?

The jars use screw-top metal lids with an airtight seal to limit exposure to air and moisture. The two-piece cap design lets you choose between a full seal or a shaker opening depending on the ingredient and use.

• Airtight metal caps reduce humidity and dust intrusion.
• Glass body resists odor retention and staining.
• Screw-top lids create a consistent, tight fit for repeated use.

What makes refilling and dispensing easier?

Every set comes with a collapsible silicone funnel sized to the jars’ 1.5" openings so you can refill powders and granules without mess. The two-in-one shaker lids include a removable insert so you can swap between a wide opening for pouring and a perforated top for shaking.

• Collapsible funnel folds flat for storage and opens for quick refills.
• Removable shaker insert allows controlled dispensing of fine or coarse spices.
• 1.5" mouth balances easy filling with secure lid placement.

Are these jars durable and easy to clean?

The jars are made from thick, food-grade, lead-free glass that resists chips and holds up to regular kitchen use. Clear glass makes contents visible at a glance and rinses clean; lids and the funnel are simple to hand-wash or wipe.

• Thick, lead-free glass for longevity and safe food contact.
• Smooth interior walls avoid trapped residue, easing cleaning.
• Metal caps and silicone funnel are low-maintenance and reusable.

What practical uses do these mini mason jars have beyond spices?

These versatile jars work for more than cooking—store DIY supplies, snacks, single-serve condiments, samples, or travel-size toiletries. Their uniform size and included labels make it easy to create a coordinated system for home, classroom, or event use.

• Craft storage: beads, glitters, small hardware, or paints.
• Food uses: custom blends, giftable spice mixes, or portioned snacks.
• Organization: screws, buttons, makeup samples, and party favors.
