The Luna Preserving Jar you know—now in an even more sustainable version. Part of our Wild Glass Collection, this design takes the classic screw-top canning jar to a new level with improved sustainability and functionality.
Most canning jars on the market aren’t truly reusable—their lids are designed for single use, often warping or deteriorating after the first seal, requiring constant replacements and creating unnecessary waste. Our Luna Preserving Jar was created to solve this problem.
Unlike traditional canning lids, the Luna Cap is made from high-quality stainless steel, designed to be used over and over again without rusting or degrading. Its lacquer-free, food-safe Pearl Seal is fully detachable, making it easy to clean and maintain, ensuring a truly reusable, long-lasting preservation system. Our patented design also includes an exclusive slot for easier vacuum release, so you can open your preserved foods effortlessly—without damaging the lid.
Crafted from 100% post-consumer recycled glass, Wild Glass significantly reduces CO₂ emissions, lowers energy consumption, and minimizes industrial waste. Each jar carries unique natural imperfections like bubbles, color variations, and organic textures—proving that sustainability can be both beautiful and practical.
Truly reusable. Built to last. Made for a waste-free future.
