Nevlers 12 oz Square Swing-Top Glass Bottles 12-Pack — Airtight Reusable Jars with Steel Closures & Accessory Kit

Nevlers 12 oz square swing top glass bottles are a 12-pack of durable, airtight refillable bottles with steel closures and accessories for bottling, gifting and home use.

These square 12-ounce glass bottles combine a classic swing-top closure with thick glass construction and a full accessory kit so you can fill, seal, label and present homemade beverages, extracts, syrups and dressings. The kit includes 12 empty bottles, a collapsible funnel, cleaning brush, gold marker, 15 shrink-wrap sleeves and 15 gift tags—everything needed to make small-batch production tidy and attractive.

How do these swing-top bottles keep contents fresh?

The wire bail and rubber gasket create a tight, reusable seal that minimizes air exposure and leakage. The heavy glass resists staining and odor retention, and the closure system can be re-used hundreds of times when handled properly.

• Rust-proof steel wire closures with firm rubber gaskets
• Airtight flip-top design for spill-free storage
• Thick glass reduces temperature shock and flavor transfer

What comes in the 12-pack kit and how does it simplify bottling?

Beyond the 12 square bottles, Nevlers includes tools and labeling supplies to streamline filling, cleaning and presentation. These extras save time and help create consistent, professional-looking bottles for sales, gifts or pantry storage.

• Collapsible funnel speeds up filling without spills
• Brush cleans narrow necks and bases thoroughly
• Gold marker, shrink sleeves and tags make labeling easy

Are these bottles suitable for hot or carbonated liquids?

The thick glass and secure gasketed closure handle typical temperature changes and light carbonation, but avoid rapid extreme temperature swings and excessive pressure from active fermentations. For safety, allow hot liquids to cool before sealing and do not use for vigorous fermenting beer or kombucha without pressure-rated caps.

• Safe for room-temperature and chilled beverages
• Dishwasher-safe once closures are removed
• Not recommended for high-pressure fermentation without specialized caps

How easy is cleaning and reusing these bottles?

Maintenance is straightforward: detach the wire closure for dishwasher cleaning, or use the included brush for hand-washing narrow necks. Rubber gaskets are removable for periodic inspection and replacement to extend service life.

• Closures removable so glass is dishwasher-safe
• Included brush reaches neck and base for deep cleaning
• Replaceable gaskets help prolong reuse
