V2 Information

Based on customer feedback from our v1 lids, we’ve created an improved v2 version with the following enhancements:

• Better Threading: Fits a wider variety of Mason jars more reliably.
• Thicker, Platinum-Cured Silicone Sealing Ring: LFGB-certified silicone rings that won't bunch up, are easier to clean, harder to lose, and compatible with many of our other lids.
• High-Quality Mold: The flip cap is now easier to open and close, stays in place while pouring, and remains leak-proof.
• Highest-Quality Polypropylene: We've upgraded to the best material for durability and safety.
• Branded Design: Now features our logo.

Just some of the many uses:

• Drinking Lid: Whether with or without a straw, these lids are perfect for almost any beverage, from protein shakes to smoothies.
• Dispenser Lid: Ideal for storing pantry items like seeds, nuts, or grains. Easily pour out flax, chia, sesame, poppy, or hemp seeds for smoothies or recipes.
• Pouring Lid: Keeps beverages like juice, kombucha, tea, or iced coffee in half-gallon Mason jars without messy dribbles. The flip cap eliminates the need to set the lid down while pouring.
• Cooking Liquid Storage: Perfect for oils, vinegars, liquid aminos, and other cooking liquids—airtight storage and clean, controlled pouring every time.
