* Daily Use: Ideal for storing leftovers, pantry staples, snacks, fermented foods, and more. Designed for everyday kitchen use. * High-Quality Materials: Stainless Steel is one of the most commonly used materials in the kitchen as it's rust proof, durable, and nonreactive. It's used to make cookware, utensils, commercial food processing equipment, and more. Stainless steel will not leach any chemicals into your food and beverages like some plastics can. LFGB is the European standard for food grade silicone, and is higher quality and more expensive than FDA food grade. It passes the pinch test. * Leak-Proof & Airtight: Full silicone liners provide a secure, spill-proof seal that helps keep food fresh and prevents leaks. * Safe & Non-Toxic: BPA-free, plastic-free, and nonreactive. These lids will not leach chemicals into your food or drinks. * Smart, Secure Fit: Thick silicone liners cover the entire interior surface for a snug fit that stays in place and is easy to clean. * Versatile & Compatible: Designed to work with our plastic lids and silicone sealing rings. Not intended for canning or heat processing. Every day in our kitchens we're reaching for storage lids to: * Keep staples fresh and the pantry organized * Put away leftovers from dinner (hello, easy lunch packing!) * Save the remainder of our kids' favorite drink or unfinished snack * Store fermented foods * Bring nuts, seeds, crackers, and other snacks on the go * Keep sauces and liquids spill proof in the fridge * And so much more! Traditional two-part tinplate lids are frustrating, fall apart, contain plastic, and will rust. That led us to create our unique, rust proof, leak proof storage lids. These premium lids are as stylish as they are practical! Made from only the highest quality materials: 18/8 304 grade stainless steel and LFGB European grade silicone rubber, you can feel good about purchasing a safe and durable product. Our silicone lid liners cover the entire inner surface of the lid (so they fit securely and won't ever drop into the jar) and create an airtight and spill proof seal. They are thick and heavy, which make them easy to clean and hard to lose. The liners are interchangeable with our plastic storage lids as well for added versatility. Our silicone sealing rings also fit these lids. Not for canning or processing.
