✨ Features
- 🔒 3-Piece Design: Separates easily for quick cleaning — no pipe cleaner needed, even if brine gets inside.
- 💧 Fill with Water, Vodka, or Sanitizer: Fill halfway to create an effective one-way seal that lets CO2 out without letting oxygen in.
- 🫙 Compatible with Silicone Fermenting Lids: Fits directly into Mason Jar Lifestyle silicone fermenting lids; other lids may require a drilled rubber stopper or grommet.
- 🧼 Dishwasher Safe: The plastic construction is fully dishwasher safe for easy, fuss-free cleaning.
- 🥦 Built for Vegetable Ferments: The 3-piece shape handles overflow far better than S-shaped airlocks, making it the smarter choice for bubbling vegetable ferments.
