Airtight Glass Container Glass Storage Containers with Lids

Smart Automatic Air Vent Technology: Engineered with an integrated automatic pressure-relief valve, the lid continually releases accumulated carbon dioxide during fermentation. This eliminates the need to manually burp the jar, preventing gas buildup and ensuring a completely safe, effortless, and failure-free fermentation environment.

Mess-Free Liquid Draining: The upgraded lid features a built-in precision strainer. You can pour out pickle brine or fermentation juices smoothly without opening the whole container or risking food spilling out—keeping your counters clean and your ingredients intact.

Ergonomic Heavy-Duty Carrying Handle: Built for real kitchen use, the sturdy top handle offers a secure, comfortable grip. It makes moving heavy, liquid-filled jars from pantry shelves to countertops or refrigerator doors safer and far more convenient.

Four Versatile Capacities for Any Recipe: Designed to cater to all your preservation needs, available in four distinct sizes: S (500 ml) for small artisanal batches or daily preserves, M (1250 ml), L (1550 ml), and XL (1950 ml) for large-capacity kimchi, kombucha, or pickled vegetable batches.

Universal Glass Jar Compatibility: Designed with standardized threading, the innovative lid system is fully cross-compatible with your existing glass jars, allowing you to instantly upgrade your current food storage setup without purchasing entirely new containers.

Crystal-Clear Square Glass Body: Crafted from high-transparency glass in a space-saving cubical shape that fits neatly into cabinets and refrigerators. The ultra-clear walls allow you to monitor fermentation progress, color changes, and bubble activity at a single glance.

Dual-Style Options (Basic & Upgraded): Choose between the streamlined Basic Style for standard everyday storage and the feature-rich Upgraded Style equipped with automatic venting and liquid straining functions.
